If you have ever towed a heavy trailer down a long mountain grade, you know that sinking feeling when your brake pedal starts getting soft. That is brake fade, and it is one of the most dangerous situations a diesel truck owner can face. The best diesel exhaust brake systems solve this problem by using your engine’s own compression to slow your truck down, saving your wheel-mounted brakes for when you actually need them.
After researching dozens of exhaust brake options and comparing real user feedback from diesel forums, installation shops, and long-haul towers, I have narrowed down the top 10 systems worth your attention. Whether you are running a Cummins, Powerstroke, Duramax, or even an Isuzu commercial truck, there is an exhaust brake solution on this list that fits your setup.
In this guide, I cover everything from complete electronic exhaust brake kits to supporting components like pressure enhancers and valve bodies that make your existing brake system work better. I also break down the buying considerations that actually matter, from vehicle compatibility to installation difficulty, so you can make the right call the first time.

Exterior: Painted
I have been looking at exhaust brake options for heavy towing applications for a while now, and the BD Diesel 2001102 keeps coming up as one of the most discussed units in diesel forums. After reviewing 17 verified user experiences, the consensus is clear: this brake makes a massive difference when you are hauling heavy loads down steep grades.
What caught my attention right away is how many owners report plug-and-play installation on their trucks. One F-550 owner mentioned it works flawlessly with a 17,000-pound trailer behind it, which is serious weight. That kind of real-world performance is exactly what you want from an exhaust brake system.
The two-phase braking design is where this unit shines. Users consistently report that the second phase delivers noticeably stronger retarding force than expected. For anyone towing through mountain terrain, that extra braking authority gives you confidence you just do not get from wheel brakes alone.
If you drive a Ford diesel truck and regularly tow loads over 10,000 pounds, this BD Diesel exhaust brake should be on your short list. It is especially effective for F-250 and F-350 owners who deal with mountain driving or long highway descents on a regular basis.
The plug-and-play nature makes it accessible even if you are not a seasoned diesel mechanic. Most owners report completing the installation in an afternoon with basic hand tools.
There are two important caveats. First, some Ford truck owners have reported their vehicle going into limp mode after installation, which appears to be a software recognition issue. Second, if you frequently drive unloaded, the Level 2 setting can feel aggressive, so you may want to keep it in the lower setting when running empty.
Also worth noting: Powerstroke engines do not handle as much back pressure as Cummins engines do. If you own a Powerstroke, keep that in mind when selecting your braking intensity level.

With 106 customer reviews and a solid 4.4-star rating, the BD Diesel Pressure Enhancer is the most widely-owned product on this list. I wanted to understand why so many diesel truck owners chose this specific component, and the answer became obvious after reading through the feedback.
This unit addresses a problem that frustrates many Ford 6.7L Powerstroke owners: shift delay and hard gear changes. It works by improving transmission line pressure control, which directly impacts how your truck behaves when the exhaust brake is engaged. When your transmission shifts smoothly, your exhaust brake system works more effectively overall.
Multiple owners describe the installation as straightforward, especially if you are already doing a transmission service. One user said it took them about 20 minutes to install while they had the transmission pan off for fluid changes. That kind of convenience matters when you are working on your own truck in the garage.
The most common feedback I see is how much smoother the downshifts become when coasting. Instead of the clunky, delayed shifts that many Ford 6.7L owners complain about, the Pressure Enhancer delivers clean, predictable gear changes. This is particularly helpful when descending grades with a load behind you.
Ford 6.7L Powerstroke owners who are experiencing shift delay, hard shifts, or poor transmission behavior during exhaust brake operation will see the most benefit from this unit. If your truck already shifts perfectly, this will not add much value. But for the majority of 6.7L owners dealing with transmission quirks, this is a cost-effective fix.
It is also a smart addition if you are planning to add or already have an exhaust brake installed, because smoother transmission operation directly improves braking effectiveness and consistency.
A few users have pointed out that this device is essentially an on/off pressure switch, so do not expect it to solve complex transmission problems. It works best on trucks with stock or near-stock power levels. If you have heavily modified your truck with aggressive tuning, the results may be less pronounced.
Overall, with over 100 reviews backing it up and a price point that is much lower than a full exhaust brake kit, this is one of the best value upgrades you can make to your Ford diesel braking setup.
Model: 1030368-V2
Weight: 2.32 oz
Made in USA
Fits: Dodge 07.5-16 68RFE
The BD Diesel Electronic PressureLoc holds the highest individual rating on this list at 4.7 stars from 18 reviews, and after reading through the feedback, I can see why. This unit is purpose-built for Dodge Ram trucks with the 68RFE transmission, and it does exactly what it promises.
What makes this product special is how directly it improves exhaust brake performance. Several owners report that their exhaust brake became noticeably more effective after installing the PressureLoc. The reason is simple: when your transmission holds gears longer and shifts more predictably, the exhaust brake can maintain consistent back pressure for better retarding force.
The installation time is genuinely impressive. Multiple users report a 5-minute plug-and-play installation. You connect it, run the transmission quick learn procedure (which your dealer or a good scan tool can handle), and you are done. For anyone who has spent a full weekend installing other diesel upgrades, this kind of simplicity is refreshing.
If you own a 2007.5-2016 Dodge Ram with the 6.7L Cummins and the 68RFE transmission, this is hands down one of the best supporting mods you can add to your exhaust brake setup. Users specifically mention that it helps keep transmission temperatures down during heavy towing, which is critical for long-term reliability.
The fact that it is made in the USA and carries a plug-and-play design makes it a low-risk, high-reward upgrade. Even if you are on the fence about exhaust brakes, this unit improves your everyday driving experience with smoother shifts and better gear holding.
You will need to perform a transmission quick learn procedure after installation. This can be done at most dealerships or with an advanced scan tool. It takes about 10 minutes, but it is a required step. Without it, your transmission will not properly adapt to the new pressure settings.
Also, if you are running higher than stock power levels, BD Diesel makes a more advanced unit called the ProTect68 that might be a better fit. The PressureLoc is ideal for stock or mildly tuned trucks.
Model: 1060605
Dimensions: 3.8x9.5x3.8 in
Material: Metal
Connector: Electrical
The BD Diesel Valve Body is a different kind of product from the full exhaust brake kits on this list, but it earns its place because of how it transforms transmission performance on Dodge trucks with the 48RE transmission. With 66 reviews and a 4.3-star rating, this is a proven solution for a very specific problem.
If you have ever experienced shuttle shifting between second and third gear on your Dodge diesel, you know how annoying and potentially damaging it can be. This valve body eliminates that problem entirely. Multiple owners report that the shuttle shift disappeared immediately after installation, and their P1757 Governor Pressure codes cleared for good.
From an exhaust brake perspective, having a properly functioning valve body is essential. When your transmission hunts between gears, it disrupts the consistent back pressure that your exhaust brake relies on. Fixing the valve body ensures your braking system can operate at peak efficiency.
Installation requires dropping your transmission pan, which takes about 2 hours for an experienced mechanic. It is not a beginner-level job, but it is straightforward if you are comfortable working around transmissions. Several owners noted that having a second person to help makes the job much easier.
This valve body is designed specifically for the Dodge 48RE transmission. If you have a different transmission, you will need a different product. Make sure to verify your transmission type before ordering.
The price is higher than pressure enhancers and switches, but most owners consider it money well spent. One user said it was the best single upgrade they made to their transmission, and that it saved them from a much more expensive rebuild down the road. If you are dealing with shuttle shift or pressure codes, this is a direct fix.
Model: 1300210
Weight: 0.5 lbs
Mount: Shift Lever
Rating: IP54
Origin: Canada
The BD Diesel Exhaust Brake Switch might seem like a simple component, but having the right switch makes a real difference in how often and how confidently you use your exhaust brake. With 69 reviews, this is one of the most widely-purchased exhaust brake accessories on the market.
The shift lever mount design means your exhaust brake control is always within thumb reach. Several owners specifically mention that having the switch on the shifter is much more intuitive than reaching for a dashboard toggle, especially when you are focused on driving with a heavy load behind you.
Installation is straightforward. The push-button design connects with quick-connect terminals, and most owners report having it wired up and mounted within 30 minutes. The IP54 rating means it handles dust and water splashes, which is important in a truck cab that sees plenty of both.
The main issue I keep seeing in reviews is the rattling. Multiple owners report a persistent rattling noise from the switch housing while driving. Some have found creative fixes like adding rubber bands or grease to dampen the vibration, but it is something to be aware of. The switch functions correctly despite the noise.
If you are installing a new exhaust brake system and need a control switch, this is the standard option. It is also a good replacement if your original BD Diesel switch has failed. The shift lever mounting position makes it easy to engage and disengage your brake without taking your eyes off the road.
For owners who do a lot of mountain driving where frequent brake engagement is needed, having a switch this accessible encourages more consistent use of the exhaust brake, which translates to better brake pad life and safer descents.
Beyond the rattling, a few owners have reported switch failure over time. At this price point, some users keep a spare on hand. If you are doing a new installation, consider whether the rattling noise will bother you during daily driving before committing to this specific switch.
Model: 1027346
Weight: 16.43 lbs
Dimensions: 18.25x10.05x7.5 in
Fit: 07.5-17 RAM 6.7L
This BD Diesel electronic exhaust brake is designed specifically for the 2007.5-2017 RAM 2500 and 3500 with the 6.7L Cummins. It is a full electronic exhaust brake system that replaces your factory setup or adds braking capability if your truck did not come equipped from the factory.
The fitment on the 4-inch exhaust is precise, which is what you expect from BD Diesel. Their manufacturing tolerances are tight, and the unit bolts up cleanly to the RAM platform. At 16.43 pounds, this is a substantial piece of hardware that feels built for the long haul.
However, I have to be transparent about the review data. With only 6 reviews and a 3.6-star average, the feedback is mixed. While 64 percent of reviewers gave it 5 stars, the remaining 36 percent gave it 1 star, with reports of units failing within about a week of installation. That is a concerning failure rate, even with a small sample size.
If you own a 2007.5-2017 RAM 6.7L Cummins and want an electronic exhaust brake that integrates with your truck’s systems, this is one of the few purpose-built options available. The electronic control means it works with your truck’s ECU for automatic engagement, which is more convenient than manual systems.
Cummins engines handle back pressure better than Powerstroke engines, so you can run this brake at higher settings with less concern about turbo stress. Many Cummins owners on diesel forums specifically recommend BD Diesel for this platform.
Given the mixed durability reports, I would recommend purchasing this through a source with a solid return policy. If the unit works correctly out of the box, most owners are happy with the braking performance. The key is confirming proper operation during the first few weeks of use. BD Diesel does stand behind their products, so reaching out to their support team is worthwhile if you experience any issues.
Model: 1031369
Weight: 2.8 lbs
Material: Alloy Steel
Fit: Ford 03-07 6.0L Powerstroke
The BD Diesel Tapshifter is a unique product that combines an exhaust brake with a tap-shifter function for Ford 2003-2007 6.0L Powerstroke trucks. With 13 reviews, this is a niche product that serves a very specific audience, and for that audience, it performs well.
The most compelling feedback from owners is how effectively this unit holds the truck back on downhill grades without using the wheel brakes at all. One owner specifically mentioned that with a 4-inch exhaust system installed, the braking performance improved noticeably over the stock pipe. That is worth knowing if you have already upgraded your exhaust.
Installation gets mixed but generally positive feedback. The instructions are described as very clear, which is critical because the wiring needs to be done precisely. Several owners emphasize that you must follow the wiring diagram step by step. Getting the transmission and PCM connections wrong means rewiring, which nobody wants to do twice.
If you are still running a 2003-2007 Ford 6.0L Powerstroke, this is one of the few exhaust brake options designed specifically for your truck with the automatic transmission. The tap-shifter integration gives you manual gear control alongside the exhaust brake function, which is particularly useful when descending with a heavy load.
The alloy steel construction and painted finish hold up well under the hood. At 2.8 pounds, it is lightweight enough that installation is manageable for a single person working in their garage.
Take photos of your wiring connections before and during installation. If something does not work correctly, having reference photos saves significant troubleshooting time. Also, verify your specific model year compatibility before ordering, as some early 2003 models have different PCM configurations.
Model: 1027348
Weight: 7620g
Fit: 13-24 Ram 2500/3500
Type: Vehicle Specific
Warranty: 30 days
This is the newest product on our list, designed for the 2013-2024 Dodge Ram 2500 and 3500 with the Cummins engine. Because it is a recent listing, there are no customer reviews yet, which makes it harder to evaluate real-world performance. However, the specifications and fitment data tell a useful story.
The vehicle-specific fit means this unit is engineered to bolt directly onto the 4-inch exhaust found on modern Ram Cummins trucks. No assembly is required out of the box, which simplifies installation significantly compared to universal fitment products that require modification.
At 7,620 grams (about 16.8 pounds), this is a heavy-duty unit that appears to share construction quality with BD Diesel’s other exhaust brake products. The electronic integration means it should work with your Ram’s existing engine management systems for automatic engagement and disengagement.
If you own a 2013-2024 Ram 2500 or 3500 Cummins and want a brand-new exhaust brake with the latest design, this is your option. The fact that it is vehicle-specific for the current Ram platform means fitment should be straightforward, and BD Diesel has a long history with Cummins applications.
The lack of reviews is the main concern. If you prefer proven products with established track records, the BD Diesel 2001102 (our Editor’s Choice) might be a better starting point. But if your truck falls outside the fitment range of older models, this newer unit is worth considering.
The 30-day warranty is shorter than I would like to see on a product at this level. I would recommend purchasing through a retailer with a good return policy and testing the unit thoroughly within the first month. BD Diesel has a solid reputation in the diesel community, which provides some confidence despite the limited review data.
Model: ISUZU
Weight: 5.2 lbs
Fit: Isuzu NPR/NQR/NRR 4HK1 5.2L
Origin: 2007-2025
If you operate an Isuzu NPR, NQR, NPR-HD, or NRR with the 4HK1 5.2L engine, finding exhaust brake options has historically been difficult. The GoTrucky exhaust brake unit fills that gap with a direct-fit design that supports multiple OEM part numbers including 8980484731, 8980484732, and 8982271650.
The construction quality appears solid based on the product specifications. The heavy-duty metal chamber has a black coating for durability, and the zinc-plated mounting bracket adds corrosion resistance, which matters for commercial trucks that operate in all weather conditions year-round.
The integrated vacuum control chamber and butterfly valve mechanism handle exhaust flow control. Pre-drilled mounting holes should make installation straightforward for anyone familiar with Isuzu truck service. The compact dimensions (11 x 6 x 5.5 inches) mean it fits without major exhaust system modifications.
For fleet managers running Isuzu commercial trucks, having a reliable exhaust brake can significantly reduce brake wear on delivery routes that include hills or frequent stops. The brake pad savings alone can justify the investment, especially on trucks that rack up 50,000-plus miles per year.
This unit covers model years from 2007 through 2025, which spans a large portion of the Isuzu commercial truck fleet currently in service. Verify your specific engine model and year before ordering to ensure proper fitment.
With zero customer reviews, I cannot speak to real-world durability or performance. The specifications look promising, and the multiple OEM part number compatibilities suggest GoTrucky did their homework on fitment. But until more Isuzu operators install and review this unit, it remains an untested option.
Model: ISUZU
Weight: 5.3 lbs
Fit: Isuzu 4HK1 5.2L and 4HE1 4.8L
Origin: 1995-2007
The second GoTrucky unit on our list covers the older Isuzu truck range from 1995 to 2007. What sets it apart is the dual-engine compatibility, supporting both the 4HK1 5.2L and the 4HE1 4.8L engines. That broader coverage makes it a versatile option for fleet operators running a mix of Isuzu models from that era.
Like the newer GoTrucky unit, this one features heavy-duty metal construction with a black-coated chamber and zinc-plated mounting bracket. The integrated butterfly valve mechanism and vacuum control chamber provide the exhaust flow restriction needed for effective braking. The pre-drilled mounting holes simplify the installation process.
This unit supports seven different OEM part numbers, which tells me GoTrucky designed it as a comprehensive replacement option for the older Isuzu platform. If you are maintaining a fleet of older Isuzu trucks, having one part number that covers multiple vehicles simplifies inventory management.
For operators still running 1995-2007 Isuzu NPR, NQR, NPR-HD, and NRR trucks, this is one of the few aftermarket exhaust brake options available. Many original equipment units are no longer available for these older models, so having a new-production replacement is valuable for keeping these work trucks on the road.
The dual-engine compatibility means you can stock one unit for trucks with either the 4HK1 or 4HE1 engine, which reduces the complexity of parts management for mixed fleets.
As with the newer GoTrucky unit, the lack of customer reviews means you are relying on product specifications rather than real-world feedback. The price point is competitive, and the build quality looks adequate from the specs, but I would recommend a thorough inspection after installation and regular monitoring during the first few months of use.
Picking the right exhaust brake comes down to five key factors: vehicle compatibility, brake type, installation complexity, towing habits, and your budget. I have broken each one down so you can make an informed decision without spending hours digging through forum posts.
The first thing you need to verify is whether the exhaust brake fits your specific truck. This means checking your engine model, model year, transmission type, and exhaust pipe diameter. A brake designed for a 6.7L Cummins with a 4-inch exhaust will not work on a 6.0L Powerstroke with a 3.5-inch pipe.
Most manufacturers provide detailed fitment guides, but I always recommend cross-referencing with forum posts from owners of your exact truck configuration. Real-world fitment feedback often catches details that manufacturer charts miss, especially for trucks with aftermarket exhaust systems or tuning modifications.
Exhaust brakes generally fall into three categories: electronic, pneumatic, and hydraulic. Electronic exhaust brakes use a servo motor to control the butterfly valve, which allows for precise back pressure management and automatic engagement through your truck’s ECU. Most of the BD Diesel products on this list are electronic.
Pneumatic systems use air pressure to actuate the valve, which is common on larger commercial trucks. Hydraulic systems use fluid pressure for actuation. For most pickup truck applications, electronic is the preferred choice because it integrates cleanly with modern engine management systems and requires less manual adjustment.
Some products on this list, like the BD Diesel PressureLoc and Pressure Enhancer, install in under 30 minutes with basic tools. Others, like full exhaust brake kits and valve bodies, require dropping transmission pans or modifying exhaust systems, which can take several hours and may need a lift.
Be honest with yourself about your mechanical skill level. If you are comfortable with basic electrical wiring and have a set of metric sockets, most exhaust brake installations are within reach. But if the idea of splicing into your truck’s wiring harness makes you nervous, budget for professional installation, which typically runs a few hundred dollars at a diesel shop.
Not everyone needs an exhaust brake. If you only tow occasionally on relatively flat terrain, your wheel brakes may be perfectly adequate. But if you regularly tow loads over 8,000 pounds, drive through mountainous areas, or haul heavy trailers on long highway routes, an exhaust brake is one of the best safety investments you can make.
Forum data from diesel truck owners consistently shows that exhaust brakes pay for themselves in extended brake pad and rotor life. Many owners report their brake components lasting twice as long after installing an exhaust brake, which is a significant savings on heavy-duty truck brake jobs that can run several hundred dollars per axle.
One concern I see frequently on diesel forums is whether exhaust brakes can damage turbos through excessive back pressure. Quality systems include pressure relief valves or bypass mechanisms that prevent back pressure from exceeding safe levels. When evaluating an exhaust brake, check whether it has built-in turbo protection features.
This is one area where brand reputation matters. BD Diesel and PacBrake both have established engineering teams that design their systems with turbo safety margins. Cheaper, no-name products may not include these protections, which puts your turbocharger at risk. Based on installer feedback from multiple diesel forums, PAC brake units tend to survive longer in harsh conditions compared to some competing brands.
An exhaust brake does not work in isolation. Products like pressure enhancers, valve bodies, and control switches directly impact how well your braking system performs. If your transmission shifts poorly or your control switch rattles itself loose, even the best exhaust brake will underperform.
Consider building a complete system rather than just buying the cheapest brake unit you can find. A pressure enhancer paired with a quality exhaust brake and a reliable control switch will outperform a standalone brake every time, and the total investment is still far less than the cost of replacing brake pads and rotors prematurely.
Yes, running an exhaust brake on a diesel truck is beneficial and safe for most driving conditions. Exhaust brakes create back pressure in the exhaust system to slow the vehicle without using wheel-mounted brakes, which prevents brake fade on long descents and extends brake pad and rotor life significantly. Many diesel truck owners report their brake components lasting twice as long after installing an exhaust brake. Modern electronic systems engage automatically when you lift off the throttle, making them convenient for daily use. The key is choosing a system with proper turbo protection features to prevent excessive back pressure.
BD Diesel is widely regarded as one of the top exhaust brake manufacturers for diesel pickup trucks, offering systems specifically designed for Cummins, Powerstroke, and Duramax platforms. PacBrake is another highly respected brand, with multiple diesel forum installers reporting that PAC brake units outlast competitors in long-term durability. For commercial truck applications, companies like Jacobs (maker of the Jake Brake) have decades of proven performance. The best choice depends on your specific truck, engine, and towing needs. BD Diesel stands out for the breadth of their product line, covering everything from full exhaust brake kits to supporting components like pressure enhancers and valve bodies.
Exhaust brakes are most efficient at higher engine RPMs when the engine is producing maximum exhaust flow. This typically occurs when the vehicle is descending a grade in a lower gear, where the engine is spinning fast enough to generate significant back pressure when the exhaust butterfly valve closes. The retarding force increases with engine speed, which is why downshifting before a long descent improves exhaust brake effectiveness. Factory-installed exhaust brakes are roughly 25 percent more efficient than aftermarket systems because they are integrated directly into the engine and exhaust design from the start.
An exhaust brake works by restricting exhaust flow with a butterfly valve in the exhaust pipe, creating back pressure that slows the engine. A Jake brake (compression release brake) works by opening the exhaust valves at the top of the compression stroke, releasing compressed air and converting the engine into an air compressor that absorbs energy. Jake brakes produce significantly more retarding force but are much louder, which is why many municipalities ban their use in residential areas. Exhaust brakes are quieter and more commonly found on pickup trucks and medium-duty vehicles, while Jake brakes are typically used on large commercial diesel engines.
Many exhaust brake systems can be installed by experienced DIY mechanics with basic hand tools and electrical wiring skills. Products like pressure enhancers and control switches typically take 20 to 60 minutes to install. Full exhaust brake kits are more complex, requiring exhaust system modification, electrical connections to the ECU, and sometimes transmission adjustments, which can take 4 to 8 hours. If you are comfortable working with electrical connectors and following detailed wiring diagrams, a DIY installation is achievable. However, if you are not confident in your mechanical abilities, professional installation at a diesel shop is recommended and typically costs a few hundred dollars.
Finding the right diesel exhaust brake system comes down to matching the product to your specific truck, your towing habits, and your mechanical comfort level. For most owners, the BD Diesel 2001102 Exhaust Brake offers the best combination of proven performance and real-world reliability. If you drive a Ford 6.7L, the Pressure Enhancer is an incredible value that improves both transmission behavior and exhaust brake effectiveness in one affordable package.
For Dodge Ram 68RFE owners, the BD Diesel Electronic PressureLoc delivers the highest satisfaction rating on this list with a dead-simple 5-minute install. And if you are running an Isuzu commercial fleet, the GoTrucky options fill a real gap in the market for both newer and older truck models.
Whatever system you choose, remember that the best diesel exhaust brake systems are the ones that get used consistently. A properly installed exhaust brake will save you money on brake components and give you the confidence to tow safely through any terrain in 2026 and beyond.
