BD Diesel Exhaust Brake Variable Vane - Chevy 2007.5-2010 LMM Duramax

When you're hauling a heavy load or heading down a steep grade in your 2007-2010 Chevrolet Silverado 2500 HD or GMC Sierra 2500/3500 HD, you want to be sure you have reliable control. This Variable Vane Brake (VVB) from BD Diesel is designed to work with the factory variable geometry turbocharger found on your LMM Duramax engine, using its existing technology to help you slow down safely and effectively.

What you get in this kit is the main control module, a dash-mounted push-button switch with a bracket and decal, the main wiring harness, and all necessary hardware for installation. The system works by electronically closing the vanes in your turbocharger, creating exhaust back pressure that resists the engine's rotation. This can generate up to 130 retarding horsepower, helping you maintain your speed on descents and curves without constantly riding your service brakes. The VVB integrates with your cruise control system, automatically adjusting to maintain your set speed, and offers three distinct modes for the Allison transmission: automatic, moderate, and aggressive downshifting programs. It also works with manual gear selections. This setup is designed to plug directly into existing factory ports, making installation straightforward.

This exhaust brake is a well-built system that can significantly improve your confidence and safety when towing or carrying heavy loads. It's backed by a 12-month or 24,000-mile warranty from BD Diesel.
