BD Diesel Exhaust Manifold Kit - 02-13 Chevy Silverado 1500 & GMC Sierra 1500 V8

This BD Diesel exhaust manifold kit gives you everything you need to replace the manifolds on your 2002-2013 Chevrolet or GMC truck with a V8 LS engine. Inside this box, you'll find the two high-silicon ductile iron exhaust manifolds, along with all the necessary new longer bolts, spacers, and gaskets required for installation. These aren't just stock replacements; they're built to address common failure points and improve durability.

What sets these manifolds apart is their robust construction and thoughtful design. They feature a uniform, increased wall thickness throughout, which helps reduce stress and prevent cracking over time. The material itself, high-silicon ductile iron, is chosen specifically to combat warping, a common issue with exhaust components exposed to extreme heat cycles. BD Diesel has also engineered adjusted mounting locations for the heat shield and uses extended fasteners, 15mm longer than stock, along with added spacers. This setup effectively reduces stress on the bolts, helping to prevent the common bolt failures that plague many factory manifolds.

The machined bolt mating surfaces ensure a secure and leak-free connection when you bolt them up. This kit is designed to fit a wide range of GM LS-based trucks, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Avalanche, and Cadillac Escalade. If you're looking to replace worn-out manifolds and want a more durable, long-lasting solution, this kit offers a solid option.
