2002-2013 GM 1500 Exhaust Manifold kit (1041400)

Experience unparalleled performance and durability with BD Diesel's enhanced Exhaust Manifold Kit, specifically designed for GM LS-based V8 truck engines. This BD-upgraded manifold addresses common exhaust manifold bolt failures by incorporating extended fasteners and spacers (15mm longer) that effectively withstand thermal expansion and reduce stress on the fasteners. Crafted with precision, these BD Manifolds boast a robust, thicker design made from high-silicon ductile iron to combat warping and cracking, ensuring your vehicle remains at peak performance for the long haul. The uniform increased wall thickness throughout the manifold reduces stress risers. The kit includes all new bolts, spacers, and gaskets, providing a complete, ready-to-install solution, and features machined bolt mating surfaces for a secure bolted joint.
