BD Diesel Performance Exhaust Brake - 01-10 Duramax w/4" Exhaust - 1024311

Increase your driving confidence and towing safety with the superior retarding performance of the BD Diesel Exhaust Brake. Using BD Diesel'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 Diesel Exhaust Brakes 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 EGTprobe, 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 Diesels 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.
