Variable Vane Exhaust Brake
The New Era Of Exhaust Brake

The variable vane turbocharger design used in the 2006-up Duramax engines to reduce turbo lag and increase power can also help slow you down. BD utilizes this technology to electronically close off the 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.

While in Tow/Haul mode, switch BD’s Variable Vane Brake (VVB) on and every time you let off the throttle, it will close the variable vanes in the turbo, developing exhaust back pressure in the engine’s combustion chamber which creates resistance against the piston from reaching top dead center.

The V.V.B. control switch offers different modes, including automatic and aggressive downshifting programs. Exhaust braking also works in Allison manual shift selections. The VVB integrates with the cruise control to automatically accelerate and decelerate to maintain vehicle speed.

On LMM applications, the Warm Up feature will close the vanes while at idle until engine temperature reaches a preset level. Great for getting your truck up to operating temperature quicker on cold mornings.

Easily and simply installs by plugging into existing factory ports and by mounting the rotary switch on your dash. All of these features in one package which with some competitors would require two separate ones at nearly twice the price and twice as long to install.  Now that is value added engine retarding at it’s engineered finest.

    Follow up review. Performance is awsome. With my 10k fifth wheel the braking effect is excellent. Even with my gooseneck loaded to a combined weight of 26,500 the effect was very good. I would recommend this product anytime.

    Installation was a breeze. Directions were pretty good, and after finding a picture tutorial it all made perfect sense. I am very happy with the performance aspect so far. The real test will come later this summer when I tow at combined weights of 26000.
