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

BD Diesel is known for building tough parts for trucks, and this driver side exhaust manifold is no exception. If you're working on a 2002-2013 Chevrolet Silverado 1500 or GMC Sierra 1500 with a V8 engine, this manifold is designed to replace your stock unit and handle the demands of your truck. It's built to address common issues like exhaust manifold bolt failures that can happen due to thermal expansion and stress.

What makes this manifold a solid choice is its construction from high-silicon ductile iron, which is much less prone to warping than standard cast iron. BD Diesel also includes longer bolts and spacers, specifically 15mm longer, to reduce stress on the fasteners and help prevent them from breaking. The mounting locations for the heat shield have been adjusted, and the bolt mating surfaces are machined for a secure connection. This manifold has a uniform increased wall thickness throughout, which helps reduce stress risers and prevent cracking over time.

This kit comes with everything you need for installation, including all new bolts, spacers, and gaskets. It's designed as a direct replacement for GM OEM part number 12616285, ensuring it fits right on a wide range of GM LS-based truck engines, including popular models like the Chevrolet Avalanche and Tahoe, and GMC Savana vans.
