Quick Ship SKU #: BD-2023331 BD Turbo Mount Exhaust Brake 04.5-05 Dodge 5.9L Cummins 2023331

Increase your driving confidence and towing safety with the superior retarding performance of the BD Brake for your Cummins! 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.

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, 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 Exhaust Gas Temperature 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 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 can even be used for other applications it's that tough.

2003-05 Dodge Cummins equipped with automatic transmission (47RE or 48RE) require a BD TowLoc or BD TorqLoc for best retarding results. This is due to the inability of the torque converter to stay in full lockup when your accelerator pedal is released. Without some type of lockup controller (TowLoc or TorqLoc) your engine will retard from the exhaust brake, but the retarding effect will not make it through the transmission, thus not slowing your wheel speed down (where you need it most!) Either of these items can be purchased separately at checkout. And as always, if you are unsure of which controller best suits you, CALL US, we're more than happy to help!

All BD Brake kits come complete with the brake, air compressor, mounting hardware and complete instructions.
