Exhaust Brake Universal 4.0 Inch Remote Mount Air Actuated BD Diesel

Braking you can use

BD has been building exhaust brakes for almost 30 years. Its Variable Orifice Technology combines a solid offset butterfly, a spring-loaded cylinder and pressure regulation to give up to 150 retarding horsepower across the rpm range, not only at high rpm.

The housing is cast iron, with BD's alumibronze bushing, piston-ring seals and a stainless steel butterfly and shaft to stand up to exhaust heat and corrosion.

This is BD's universal-install version, sized for a 4 in exhaust and air actuated, for applications without a vehicle-specific BD kit.

Who it's for

Owners of trucks, motor homes and other diesel applications without a vehicle-specific BD kit who want an exhaust brake for long grades.
