Pacbrake PRXB Exhaust Brakes

Thoroughbred Diesel is your source for Pacbrake PRXB exhaust brakes for your GM Duramax, Ford Powerstroke, and Dodge Cummins diesel. Shop below for Pacbrake PRXB exhaust brakes for Diesel Trucks. Pacbrake exhaust brakes are relatively maintenance free when used at every opportunity. However, to get the maximum amount of trouble free service a few areas require periodic lubrication. Applying Pacbrake’s synthetic lubricant Superlube to the moving parts at every oil change will eliminate waring and seized parts problems.

Provides 50% More Braking Power at Lower RPM’s
PRXB gives you the BEST holdback in the 1400-1800 RPM range (where you typically drive). Better than any standard exhaust brake on the market.

Patented 90° Non-contacting Butterfly Valve
Specially engineered to prevent sticking.

Arcor® Nitride Coating
Pacbrake’s industry exclusive Arcor® coating increases resistance to wear and corrosion while strengthening the exhaust brake and adding lubricity.

Unique Backpressure Limiter
Protects against engine overpressure

Easy Maintenance
Maintenance is as simple as using the exhaust brake on a regular basis and applying Superlube periodically (multi-purpose heat resistant lubricant which helps to prevent rust and corrosion).

Built-In Warm Up Option
The Pacbrake has been designed to automatically turn on at idle and stay on until the coolant temperature reaches 170-175 degrees. It will then disengage.

Unrestricted Exhaust Flow
Won’t interfere with power output.

No Gaskets Required
Precision machined surfaces eliminate the need for gaskets and risk of leakage.

Custom Housing
Pacbrake exhaust brakes are designed specifically for individual engine applications to maximize performance and reliability. They are not a one size fits all compromise.
