BD Diesel Brake - 2004.5-2010 Duramax 6.6L LLY/LBZ/LMM w/Stock Exhaust

BD Diesel has been a well-known name in the diesel performance world for decades, and they're known for making tough, reliable parts. This exhaust brake is a prime example, built to help you control your truck and trailer on those long, steep descents. When you're towing a heavy load, especially down a mountain, relying solely on your service brakes can lead to overheating, brake fade, and costly repairs. This BD exhaust brake works by restricting exhaust flow, creating back-pressure that helps slow your engine down, saving your service brakes and giving you more confidence on the road. It's designed to fit a wide range of Duramax 6.6L trucks from 2001 to 2010, including popular models like the Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD.

BD's design incorporates their exclusive Variable Orifice Technology, which means it provides consistent retarding power throughout the engine's RPM range, not just at higher speeds. This is achieved through a solid, offset butterfly valve that's spring-loaded for precise control. The housing is made of rugged cast iron, and critical internal components like the bushing and piston ring seals are made from AlumiBronze for durability. The butterfly valve and shaft are stainless steel to resist corrosion from exhaust heat and gases. Many kits, including this one, come with a powerful air compressor that's built tough enough to handle other air-powered accessories like air horns or airbags. For automatic transmissions prior to 2006, BD offers optional kits to manage torque converter clutch engagement, ensuring peak performance and lower transmission temperatures.

This kit includes the exhaust brake assembly, necessary tubing, a control kit, and all mounting hardware, which is made from corrosion-resistant stainless steel. It also features a port to monitor the brake's retarding performance, and most kits include an EGT port. BD backs this exhaust brake with a 24-month or 24,000-mile warranty, giving you peace of mind with your investment.
