Exhaust Brakes
BD's 3" vacuum cylinder with a progressive spring loaded piston delivers 100 psi apply & release pressure. The exclusive alumibronze bushings prevent shaft sticking. The free flowing elbow casting incorporates an off set stainless steel butterfly. Once the engine has reached the peak retarding pressure the offset butterfly compresses the spring and calibrates the retarding HP. It beats anything else in the industry!
BD's casting simply bolts in place of an existing elbow. It’s attached into the trucks vacuum system for control. No engine modifications are needed on the 24 valve engines. For peak retarding power on the 12-valve engine we have H/D exhaust springs available. |
