Product Information

Whether your motivation is fueled by safety or maintenance cost savings, you have found the best alternate supplemental diesel exhaust braking system, next to an engine brake, that guarantees optimum retarding performance through the entire RPM range. Unlike a typical exhaust brake that requires high RPMs to work properly, the patented PRXB (pressure regulated exhaust brake) delivers constant exhaust backpressure (braking) as early as 1200 RPM through to the maximum allowable RPM. No other diesel exhaust brake can claim this!

At 1/2 the price of an engine brake, and virtually maintenance free, Pacbrake's PRXB exhaust brake will save you money. It is ideal for in city driving but most importantly for steep descents. Take your foot off the accelerator, and instantly feel the hold back without touching your service brakes – feel in control!

Pacbrake’s PRXB Exhaust Brake has revolutionized the braking industry. Adapted for a variety of diesel vehicle applications, the PRXB provides the strongest braking horsepower, greatest speed reductions and shortest stopping distances possible without the use of service brakes. Diesel engines, unlike gasoline engines, don't slow down simply by taking your foot off the accelerator; they rely on service and supplemental brakes. An exhaust brake is a form of a supplemental brake, and they work much differently than their conventional counterparts. 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.
