BD Diesel Exhaust Brake Variable Regulating Back-Pressure System

BD Diesel Exhaust Brake Variable Regulating Back-Pressure System Maximize control and safety on steep descents. The BD Diesel Variable Regulating Back-Pressure Exhaust Brake reduces brake fade, lowers service brake wear, and prevents costly repairs by providing reliable, adjustable engine retarding power for heavy loads and trailers. Key Features Proven variable back-pressure design — industry-trusted performance for consistent retarding. Flexible mounting — turbo-mount bolts in place of the factory elbow or inline design installs between engine and muffler/DPF/cat. Rugged construction — cast-iron housing with AlumiBronze bushing and positive sealing piston ring to resist carbon and rust. Reliable actuation — newer models use an air cylinder; earlier units use a powerful 3" vacuum cylinder. Included compressor — later kits include a durable air compressor useful for air horns, airbags and air-ride hitches. Easy control — lighted On/Off toggle switch or optional stick-mounted rocker for manual transmissions; interfaces with engine idle verification for quick engagement. Transmission support — programmable AutoLoc and PressureLoc kits available for pre-2006 automatics to reduce torque converter slip and lower transmission temps. Complete kits — supplied with brake assembly, compressor (when applicable), mounting hardware, monitoring port, installation instructions and many models include an EGT port. Benefits Improve downhill control, extend service brake life, reduce repair costs and maintain peak retarding performance under heavy loads. BD Diesel's durable design ensures miles of leak-free operation and dependable braking when you need it most.
