Description

The PRXB Exhaust Brake provides 50% more braking power at 1400-1800 RPM. It features a spring-controlled pressure-regulated mechanism to prevent engine overpressure and a patented 90-degree non-contacting butterfly valve for maximized backpressure and anti-seizing. Housing and components have an Arcor nitride coating for enhanced wear and corrosion resistance, strength, and lubricity. Kits include the PRXB Exhaust Brake, controller (if needed), and a Pacbrake Onboard Air Kit (HP325 Series Compressor, 0.5 Gal Air Tank, 25 ft Coiled Air Hose, Air Accessories, and Fittings Kit).
