Introducing the Pacbrake PRXB
2 3/4" Fixed Orifice Exhaust Brake Kit (Vacuum Actuated) DirectMount- Automatic
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.
PRXB Exhaust 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.
SUPERIOR TURBO DIRECTMOUNT®
Installs easily with no welding or special tools. Bolts on with no engine modification.
Pacbrake technology results in a brake with precision machining. Our fit onto the turbo is so tight, there is no need for gaskets commonly used with other exhaust brakes.
MAXIMUM RETARDING/BRAKING POWER
In controlled tests using standard transmissions, Pacbrake will exceed or match any competitive brake on the market. Our Pacbrake offers an unrestricted flow design and provides maximum retarding power without reducing power output. A backpressure limiter guarantees engine safety.
Pacbrake has designed its Dodge brake to be installed in less than 2 1/2 hours without cutting or welding. It is simply bolted onto the truck. Some exhaust brake models require cutting, welding, and removal of the fenders and wheels for proper installation.
ARCOR® NITRIDED HOUSING & COMPONENTS
Pacbrake's industry exclusive "coating process" makes Pacbrake the toughest, most durable brake on the market. The Arcor coating also:
Reduces wear and increases corrosion resistance. Many other brakes are more susceptible to corrosion and seizing in the harsh exhaust environment.
Adds strength & maintains flawless action.
This kit is designed for the late 1988-1998 12V Dodge Cummins Only.
With automatic transmissions we recommend an aftermarket torque convertor and a lockup device of some kind (ATS Commander, Magic Switch, etc.) to achiece optimal exhaust brake performance.$902.91
