What Makes PRXB So Revolutionary?

Pacbrake's New Constant Backpressure Exhaust Brake maximizes braking power with optimum retarding performance.

Compared with a traditional fixed orifice exhaust brake the New PRXB:

• Automatically adjusts for lower RPM's
• Almost no need to manually downshift, the PRXB becomes invisible to the driver
• Higher mid range retarding power than a standard fixed orifice exhaust brake
• Almost constant retarding torque
• (35%) 1/3 more retarding power than a standard fixed orifice exhaust brake at 1500 RPM
• Seamless integration into the engine and transmission ECM's

The PRXB provides an excellent alternative to an engine brake with features including:

• 3/4 the retarding horsepower and a unique design making it ideal for in-city driving or steep downhill descents
• Quiet enough to be used in areas where engine brakes are prohibited allowing for added control in any situation
• 1/4 the weight of an engine brake
• 1/2 the price of an engine brake

Superior Turbo Directmount

• Installs easily with no welding or special tools.
• Bolts on with no engine modification.

Precision Fit

• Pacbrake technology results in PRXB with precision machining.
• The fit onto the turbo is tight; there is no need for gaskets commonly used with other exhaust brakes.

Easy Installation

• Pacbrake has designed PRXB 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.
• PRXB can replace a traditional exhaust brake with no hassle due to their same packaging envelope allowing for upgrade.

Arcor® Nitrided Housing & Components

• Pacbrake's industry exclusive "coating process" makes Pacbrake the toughest, most durable brake on the market.
• The Arcor® coating reduces wear and increases corrosion resistance. It adds strength to the brake and helps to maintain flawless action.
• Many other brakes are susceptible to corrosion and seizing in the harsh exhaust environment.

Built-in Warm Up Option

• The PRXB has been designed to automatically turn on at idle and stay on until the coolant temperature reaches 170-175 degrees. It then disengages automatically.
• Simple and comfortable.
