Pac-Brake PRXB Exhaust Brake for 98.5 - 2007 Cummins
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.
