BD Diesel Exhaust Brake - Universal 4.0in c/w Air Compressor

When you're hauling heavy loads or navigating steep downhill grades, having reliable braking power is crucial. This BD Diesel exhaust brake is designed to give your diesel truck significant extra retarding force, helping to save your service brakes and provide a more controlled descent. It works by restricting exhaust flow, using engine backpressure to slow the vehicle down, which is especially helpful when towing or carrying heavy cargo.

BD Diesel has been refining their exhaust brake designs for decades, and this model incorporates their exclusive Variable Orifice Technology. This means it offers up to 150 retarding horsepower across the engine's entire RPM range, not just at higher speeds, giving you consistent braking support. The butterfly valve and rotating shaft are made from stainless steel to resist corrosion from exhaust heat and gases, and the rugged cast-iron housing is built to withstand harsh conditions. Inside, you'll find BD's exclusive alumibronze bushing and piston ring seals, designed for durability in high-heat environments. This kit also includes a pneumatic spring-loaded cylinder for adjustable pressure regulation and an IP67 sealed air compressor, making it a complete package for many modern diesel trucks.

This universal kit is designed for 4.0-inch exhaust systems and comes with all the necessary mounting hardware, air tubing, a toggle switch, and a regulator assembly. It's a well-built system intended to provide reliable, long-lasting performance when you need it most. For installation, it's recommended to refer to the manufacturer's instructions for specific details regarding your vehicle's exhaust and electrical system.
