BD Diesel Exhaust Brake Universal 4" w/ Air Compressor

It has been almost 30 years since we started shipping our first exhaust brakes. With that many hill and mountain roads experienced, we used the knowledge gained to continue to deliver the best designed exhaust brake for your application. Incorporating BD's exclusive Variable Orifice Technology, BD's solid, offset butterfly, spring loaded cylinder and pressure regulation provides up to 150 retarding horsepower throughout the engine's RPM range - not just at high rpm like some designs that use holes or additional parts and claim it as a better idea. A range of rugged, cast-iron housings for Dodge, Ford, Chevy and motor home applications that incorporate BD's exclusive alumibronze bushing, piston ring-seals and stainless steel butterfly shaft has proven to stand-up under the harsh, high heat conditions of the exhaust environment. BD's butterfly valve and rotating shaft are made of stainless steel to resist corrosion. An air compressor is included in most kits for newer pick-up trucks.

The BD name became recognized in 1989, when the company introduced the first exhaust brake for the burgeoning Diesel pick-up truck market. BD's roots, however, actually date back to 1972, when Valley Fuel Injection Ltd. (VFI) first opened its doors. Today, Valley Fuel Injection and BD Diesel Performance are one, with specialty divisions that focus on Diesel power train components.

Our goal is to be an innovative company and a world class manufacturer that distributes products Worldwide for North American Diesel vehicles.; BD Diesel Performance is unique among its peers.
