Part # 2001030
With the change in technology as the newer truck models rolled out of the plant, BD has changed as well to apply our over 20-years of braking technology to match. With the newer Chevy Duramax engines, the change was already there, we just had to utilize it for your engine retarding needs.
The same Garrett variable vane turbo design is used in the 2004.5-up Duramax engine to reduce turbo lag and increase power can also help slow you down. BD utilizes the variable technology built into the turbo by closing off the vanes while retarding creating up to 35psi of back pressure.
Ample retarding horsepower to help maintain your speeds on descents and curves giving you better control of your truck and load.
While in Tow/Haul mode, switch BDs Variable Vane Brake on and every time you let off the throttle it will close the variable vanes in the turbo which develops exhaust back pressure in the engines combustion chamber, creating resistance against the piston from reaching top dead center.
YES! Most of the connection is done via an existing diagnostic port on the engine making for an easy and clean installation.
Not at all BD has designed their brake to not make harsh downshifts into lower gears that can cause tire chirp and drive train strain. The Variable Vane Exhaust Brake is also firmware updateable via the internet using your computer's USB connection and is the perfect fit for your Duramax towing needs.
