The Original Exhaust Brake for Diesel Pick-Up Applications!
Increase your driving confidence and towing safety with the superior retarding performance of the BD Brake for ’89-’06 5.9 liter Cummins engines. Using BD’s exclusive Variable Orifice Technology, BD’s turbo-mount design bolts in place of the factory elbow between the turbo and the exhaust system, providing peak retarding power throughout the engine’s rpm range—not just at high rpm like other brands. Our remote-mount models, meanwhile, mount in the exhaust pipe and are perfect for modified applications that may use an aftermarket turbo.
Designed for years of reliable operation, the BD Brake’s rugged cast-iron housing incorporates BD’s exclusive AlumiBronze bushing and piston ring-sealed, stainless steel butterfly shaft that has proven to stand up under the harsh, high-heat conditions of the exhaust environment. Actuated by an air cylinder (newer models) or a powerful, three-inch vacuum cylinder (earlier models), the offset butterfly valve won’t stick, and has been strategically placed in the elbow so that it won’t impede exhaust flow when in the open position. The BD brake incorporates a threaded port for mounting an EGT probe, as well as a 1/4-inch stainless steel port that can be used to monitor the brake’s retarding performance. Got a modified or twin-turbo application? BD’s remote-mount or vacuum-actuated four-inch kits are an effective solution.
Controlled by a lighted On/Off toggle switch for automatic transmissions, or stick-mounted rocker switch for manual transmissions, the BD brake communicates with the engine’s electronic idle verification board for quick engagement. The durable air compressor included in later model kits can even be used for other applications—it’s that tough.
Automatic-equipped trucks prior to 2006 require BD’s programmable Tow Loc and Pressure Loc kits to electronically control torque converter clutch engagement. This addition effectively reduces slippage, resulting in peak retarding performance as well as lower transmission temperatures.
All BD Brake kits come complete with the brake, air compressor (where applicable), mounting hardware and complete instructions.
