BD Diesel Exhaust Brake – Variable Orifice Technology

For nearly 30 years, BD has been refining and delivering the most trusted exhaust brakes in the diesel industry. Designed for mountain roads and heavy loads, BD’s exhaust brakes are built using the knowledge gained from decades of real-world use. Incorporating exclusive Variable Orifice Technology, this brake delivers up to 150 retarding horsepower across the engine’s RPM range—not just at high RPMs like others on the market. This consistent performance comes without relying on holes or gimmicks.

BD’s rugged, cast-iron housings are engineered for durability and include premium features like stainless steel butterfly shafts, alumibronze bushings, piston ring seals, and spring-loaded cylinders. The solid offset butterfly valve ensures effective performance, while the included air compressor in newer pickup kits simplifies installation. All mounting hardware is included.
