Pac Brake PRXB 2003-2004 Dodge Ram Cummins Auto trans

Introducing the Pacbrake PRXB 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. Pacbrake’s automotive products consistently outperform the competition year after year. 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
