Product Description
The BD DIESEL 1041402 Driver Side Exhaust Manifold is a heavy-duty replacement manifold engineered for 2002–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with LS-based V8 engines. Factory manifolds are well-known for bolt failures, warping, and sealing issues caused by heat cycling. BD Diesel solves this problem with a thicker, stronger manifold casting and improved hardware that helps withstand thermal expansion and reduce fastener stress.
This manifold is built from high-silicon ductile iron to resist cracking and warping under load. BD’s upgraded design features uniform increased wall thickness to reduce stress risers, plus longer bolts and spacers to improve clamp load and reduce the likelihood of snapped exhaust bolts. The kit includes new gaskets and mounting hardware for a complete, leak-free repair.
