About PacBrake
PACBRAKE EXHAUST BRAKES

Pacbrake is a manufacturing company based out of Langley, British Columbia that began operations in 1961, specializing in exhaust and engine brakes for commercial truckers, loggers, and the military. Today, their expertise still lies on exhaust braking solutions, but it goes well beyond this and into numerous other vehicle upgrades such as air suspension, air compressors, complete air management solutions, and so much more.

PACBRAKE EXHAUST BRAKES

Diesel Power Products is proud to offer the complete line of Pacbrake PRXB Exhaust Brakes for Cummins, Duramax and Powerstroke diesels. At the time of their release, the PRXB line of brakes was unlike any other, and still maintains superiority over many alternatives to this day. So what does PRXB mean and how does it work? PRXB stands for "Pressure Release Exhaust Brake." Basically, all exhaust brakes have to release a certain amount of exhaust, otherwise it would cause excessive backpressure to the engine and cause damage. However, PRXB's are unique in that they have a variable release so that as RPM's slow down, so does the release of exhaust, equating to better retarding power at lower RPM's. If you tow with your diesel and don't have an exhaust brake, you're simply missing out on the peace of mind and safety that it delivers. Pacbrake's kits come complete, even torque converter lockup controllers when applicable, exhaust adapters for aftermarket oversized exhaust, and more.
