Pacbrake PRXB Exhaust Brakes offer the highest braking power to lowest price ratio, used in US Army's Stryker Wheeled Vehicles. This kit provides 50% more braking power at lower RPMs (1400-1800 RPM range) and features a spring-controlled, pressure-regulated mechanism to prevent engine overpressure. It includes a patented 90-degree non-contacting butterfly valve to maximize backpressure and prevent seizing. Components are treated with Arcor nitride coating for increased wear, corrosion resistance, and lubricity. Each kit comes with a PRXB Exhaust Brake, Controller (if required), and Pacbrake Onboard Air Kit (HP325 Series Compressor, 0.5 Gal Air Tank, 25 Foot Coiled Air Hose, Air Accessories and Fittings Kit), along with Heavy Duty Exhaust Valve Springs.
