Description
Pacbrake’s flagship product, the PRXB (pressure regulated exhaust brake), is the unquestioned leader in the supplemental brake industry. The patented PRXB design delivers the strongest braking horsepower, greatest speed reductions and shortest stopping distances possible without the use of service brakes. It maintains optimum retarding performance by maximizing the exhaust backpressure throughout the entire RPM range. Unlike a typical exhaust brake, which requires high RPMs to work properly, the PRXB delivers constant exhaust pressure (braking) as early as 1200 RPM through to the maximum allowable RPM.
Controlled by a master ON/OFF switch, Pacbrake’s exhaust brakes provide whisper quiet supplemental braking that allows service brakes to be used much less, ultimately saving you money. They have the ability to be left on all the time, making it ideal for in-city driving or for steep, downhill grades. This product pays for itself as less wear on the brake pads means fewer brake jobs.
FEATURES
- Stainless steel sealed air cylinder with high performance seals
- Maximum allowable exhaust backpressure. Factory preset limit designed to meet the requirements set by the engine manufacture
- Both mounting surefaces are machined, therefore, eliminating the need for gaskets

- When not activated, exhaust flow in unrestricted and doesn’t interfere with the power output
- 90 degree closing, non-contacting butterfly valve guarantees engine safety while preventing sticking
- Optimum retarding performance is maintained by maximizing exhaust backpressure throughout the entire RPM range
- Kit includes Air Tank, Hose, and Accessory kit.
NOTE: This kit works with both standard and automatic transmissions. However, trucks with automatic transmissions will require a transmission controller.
