Pacbrake

Extreme braking performance

Pacbrake's New Pressure Released Exhaust Brake (PRXB) is engineered to maximize the exhaust backpressure throughout the entire RPM range making it ideal for in-city driving or downhill descents.

Compare the PRXB with standard exhaust brakes:

Automatically adjusts for lower RPM.
Almost no need to manually downshift, the PRXB becomes invisible to the driver.
Higher mid range retarding power than a standard exhaust brake.
Almost constant retarding torque.
Up to 1/3 more retarding power than a standard exhaust brake at 1500 RPM
Seamless integration into the engine and transmission ECM's.
Exact fit makes for easy upgrade from standard exhaust brake.

Pacbrake Exhaust Brake Features:

Superior Design: Pacbrake DirectMount® design mounts on the turbocharger, offers more consistent retarding horsepower, increased reliability and the easiest installation.

Maximum Retarding Power: Factory preset to allowable exhaust backpressure limit.

Designed Specifically: Pacbrakes are designed for individual engine applications for maximum performance and reliability. They are not a "one size fits all" compromise.

Unlimited Mileage Warranty: Limited warranty-two years unlimited mileage warranty on brake assembly and 1 year unlimited mileage on attaching & related components.

Positive Pressure Sealing System: Spring loaded pressure seal eliminates exhaust gas leakage into engine compartment.

Backpressure Limiter: 90° closing, mom-contacting alloyed valve plate allows more consistent retarding power while guarantying engine safety.

Precision Mounting Surface: Both contacting surfaces are machined, eliminating the need for a gasket.

Arcor® Nitrided Housing & Components: Industry exclusive process that increases resistance to wear and corrosion while strengthening and adding lubricity. (available for most models)

Freeflow Exhaust: Unrestricted exhaust flow design won't interfere with power output.
