The variable vane turbocharger design used in diesels today to reduce turbo lag, emissions and increase power can also be used to slow you down. BD utilizes this technology by electronically closing off the turbine vanes which can create up to 130 retarding horsepower. This braking force will help to maintain your speeds on descents and curves, giving you better control of your truck and load.
How it works: Using BD’s exclusive Variable butterfly Technology, providing peak retarding power throughout the engine’s rpm range unlike some models that rely on a hole/orifice within the butterfly to calibrate back-pressure only in the higher engine RPM .
Where it mounts: This exhaust brake is BD’s turbo-mount design which bolts in place of the factory elbow between the turbo and the exhaust system.
The advantage to regulating the butterfly vs. other brands is: The Butterfly is constantly exercising thus reducing the possibility of carbon and rust deposit forming that can cause premature ware and binding. Furthermore no maintenance or lubricating is required providing miles of trouble free service. The BD Brake’s rugged cast-iron housing incorporates BD’s exclusive AlumiBronze bushing and positive sealing piston ring, no blind holes for carbon and rust to form, and miles of leak free retarding. Stainless steel butterfly shaft that has proven to stand up under the harsh, high-heat conditions of the exhaust environment, 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. Brake valve is actuated by a powerful, three-inch vacuum cylinder.
Automatic-equipped trucks prior to 2006 require BD’s programmable AutoLoc or TorqLoc kit 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, port to monitor the brake’s retarding performance, complete instructions and most models come with EGT port.
This Product also comes with BD Diesel Performance’s 24 Month/24,000 Mile Parts and 12 Month/12,000 Mile Labor Warranty.
Note: Trucks with automatic transmissions are suggested to also install an AutoLoc for electronic controlled lock-converters, or, a lower stall converter for manual or no lock-up converters. Exhaust Back Pressure test gauge kit 1030050 suggested for the set-up of exhaust brakes.
