# BD Diesel Exhaust Brake Variable Vane - Chevy 2006-2007 LBZ Duramax The variable vane turbocharger design used in the 2004.5-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 BDs 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 engines combustion chamber which creates resistance against the piston from reaching top dead center.The VVB rotary switch offers three different modes included automatic moderate and aggressive downshifting programs for the Allison transmission to give better weight control. 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.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 its engineered finest. - Integrated with the cruise control to automatically accelerate and decelerate to maintain vehicle speed - Electronically closes off turbocharger vanes to provide engine braking - Electronically Closes Off Turbo Vanes To Provide Engine Braking - Integrated with CC To Auto Accel./Decelerate To Maintain Speed - Easily Installs By Plugging Into Existing Factory Ports - Delivers Up To 30-40 PSI Exhaust Backpressure - Delivers up to 30-40psi exhaust backpressure - Helps Maintain Speeds On Descents And Curves - Better control of your truck and load. - Better Control Of Your Truck And Load - 12 Months or 24000 Mile Warranty - Switch Mounted On The Dash - Switch mounted on dash This Part Fits: Year Make Model Submodel 2006 Chevrolet Silverado 2500 HD LS 2006-2007 Chevrolet Silverado 2500 HD LT 2007 Chevrolet Silverado 2500 HD LTZ 2006-2007 Chevrolet Silverado 2500 HD WT 2007 Chevrolet Silverado 2500 HD Classic LS 2007 Chevrolet Silverado 2500 HD Classic LT 2007 Chevrolet Silverado 2500 HD Classic WT 2006 Chevrolet Silverado 3500 LS 2006 Chevrolet Silverado 3500 LT 2006 Chevrolet Silverado 3500 WT 2007 Chevrolet Silverado 3500 Classic LS 2007 Chevrolet Silverado 3500 Classic LT 2007 Chevrolet Silverado 3500 Classic WT 2007 Chevrolet Silverado 3500 HD LT 2007 Chevrolet Silverado 3500 HD LTZ 2007 Chevrolet Silverado 3500 HD WT 2006 GMC Sierra 2500 HD SL 2006-2007 GMC Sierra 2500 HD SLE 2006-2007 GMC Sierra 2500 HD SLT 2006-2007 GMC Sierra 2500 HD WT 2007 GMC Sierra 2500 HD Classic SL 2007 GMC Sierra 2500 HD Classic SLE 2007 GMC Sierra 2500 HD Classic SLT 2007 GMC Sierra 2500 HD Classic WT 2006 GMC Sierra 3500 SL 2006 GMC Sierra 3500 SLE 2006 GMC Sierra 3500 SLT 2006 GMC Sierra 3500 WT 2007 GMC Sierra 3500 Classic SL 2007 GMC Sierra 3500 Classic SLE 2007 GMC Sierra 3500 Classic SLT 2007 GMC Sierra 3500 Classic WT 2007 GMC Sierra 3500 HD SLE 2007 GMC Sierra 3500 HD SLT 2007 GMC Sierra 3500 HD WT ## Details - **Price:** 1091.55 CAD - **Vendor:** BD Diesel - **Type:** Exhaust Brakes ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 1091.55 CAD | In stock | ## Images - Photo - Primary - Photo - Primary - Photo - Primary - Photo - out of package - Photo - out of package - Logo Image --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/bd-diesel-exhaust-brake-variable-vane-chevy-2006-2007-lbz-duramax) > Updated: 2026-06-26
