BD Diesel Driver Side Exhaust Manifold – Part # 1041402

Upgrade your GM LS engine-equipped truck with the BD Diesel 1041402 driver side exhaust manifold, engineered for enhanced durability and performance. Crafted from high-silicon ductile iron, this manifold features a thicker wall design that significantly reduces stress concentrations and minimizes the risk of cracking under high thermal loads. The design includes extended bolts and spacers, specifically 15mm longer, to alleviate stress on fasteners, ensuring a more secure and long-lasting installation. To improve heat management and prevent warping, the manifold incorporates adjusted mounting locations for the heat shield, maintaining optimal engine bay temperatures and protecting surrounding components.
This exhaust manifold is a direct OEM replacement for 2002-2013 GM LS-based trucks, offering a reliable upgrade for those seeking increased durability over stock parts. The kit includes all necessary new bolts, spacers, and gaskets, simplifying installation and ensuring a proper fit. Machined bolt mating surfaces provide a secure, leak-free seal, while the heat shield mounting bosses facilitate proper heat shield placement, further enhancing thermal protection. Certified under SEMA (No. SC-BDD01-0136), this manifold is designed to withstand the demanding conditions of heavy-duty fleet and performance applications, providing consistent exhaust flow and longevity.
Whether you’re restoring a fleet vehicle or upgrading your personal truck, the BD Diesel 1041402 driver side exhaust manifold offers a robust solution built with precision engineering and high-quality materials. Designed to address common exhaust manifold bolt failures and warping issues, this component ensures your vehicle maintains optimal exhaust flow, reduces the risk of leaks, and prolongs engine life by effectively managing heat and stress. Trust in BD Diesel’s longstanding reputation since 1985 for delivering heavy-duty automotive components that meet the highest standards of performance and durability.
