Pacbrake PRXB "Manual Trans"

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.

    PacBrake for the win

    Posted by Phil from Tn on Sep 23rd 2022

    I'm building a 7.3 platform for HotShoting. With the loads I intend to carry an exhaust brake is essential for driveability and safety. I haven't pulled a load yet and I have a T4 turbo with a ZF transmission. I can see where this brake will save tons on brakeware. As it is when coming to a stop an upshift to keep the rpms up with the brake engaged pulls the speed right down even with the empty 40ft trailer behind it. Very impressive. I hardly have to use the brakes at all, just the few final feet. This brake is the bomb. Now I'm going to tap into the air tank for onboard air for the airbags. Win Win and well worth it.
