Description

The Pacbrake PRXB (Pressure Regulated Exhaust Brake) is an inline-mount exhaust brake designed to provide superior retarding power comparable to a compression release engine brake, but at a lower cost. Its patented wastegate design regulates exhaust backpressure consistently across the entire RPM range, ensuring maximum braking power at all times. It is known for its performance, safety, and durability, reducing the need for service brake usage, especially in city driving or on steep grades.
