BD Diesel Exhaust Manifold Kit – Part # 1041400

Experience improved exhaust flow and durability with the BD Diesel exhaust manifold kit designed for 2002-2013 GM LS engine trucks, including Chevrolet Silverado 1500 and GMC Sierra 1500 models. Crafted from high-silicon ductile iron, this manifold set features a thicker wall design to resist warping and cracking under high thermal stress, ensuring long-lasting performance. The kit includes all necessary components—longer bolts, spacers, and gaskets—that help reduce stress on fasteners by utilizing 15mm longer bolts and spacers, which effectively mitigate common bolt failures. Machined mating surfaces guarantee a secure, leak-free connection, while the adjusted mounting locations for the heat shield facilitate proper fitment and heat management. These manifolds are engineered to meet OEM standards and are SEMA certified, providing a reliable upgrade for heavy-duty applications. Proper installation involves replacing the entire assembly with compatible fasteners and gaskets, maintaining the integrity of your engine’s exhaust system and optimizing performance. Designed for fleet and automotive use, this kit supports enhanced thermal capacity and structural strength, ensuring your vehicle maintains peak performance even under severe towing and driving conditions.

Features:

• Heavy-duty exhaust manifold built from high-silicon ductile iron for superior durability and resistance to warping

• Increased wall thickness throughout the manifold reduces stress risers and prevents cracking

• Includes longer bolts (15mm longer), spacers, and gaskets for reduced fastener stress and improved fitment

• Machined bolt mating surfaces ensure secure, leak-free sealing and proper assembly
