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 BDs exclusive Variable Orifice Technology, BDs turbo-mount design bolts in place of the factory elbow between the turbo and the exhaust system, providing peak retarding power throughout the engines rpm rangenot 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 Brakes rugged cast-iron housing incorporates BDs 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 wont stick, and has been strategically placed in the elbow so that it wont impede exhaust flow when in the open position. The BD brake incorporates a threaded port for mounting an Exhaust Gas Temperature probe, as well as a 1/4-inch stainless steel port that can be used to monitor the brakes retarding performance. Got a modified or twin-turbo application? BDs 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 engines electronic idle verification board for quick engagement. The durable air compressor included in later model kits can even be used for other applicationsits that tough.
Automatic-equipped trucks prior to 2006 require BDs 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.
Note: Not for use with aftermarket turbos
