The BD Diesel 1041401 passenger side exhaust manifold is engineered for 2002-2013 GM LS-based trucks, including Chevrolet Silverado 1500 and GMC Sierra 1500 V8 models. Constructed from high-silicon ductile iron, this manifold offers superior resistance to warping and cracking under severe thermal conditions. Its enhanced design features a thicker wall throughout to reduce stress risers, extending the service life and maintaining optimal exhaust flow. The manifold is a direct OEM replacement, providing a reliable upgrade that addresses common failure points such as bolt fatigue and heat-related stress.
This BD Diesel exhaust manifold includes extended fasteners and spacers—15mm longer than standard—to reduce stress on mounting bolts, thereby minimizing the risk of bolt failure. The kit also contains new gaskets and machined bolt mating surfaces for a secure, leak-free fit. Additionally, the design incorporates adjusted mounting locations for the heat shield, improving heat management and protecting surrounding components. The assembly’s robust construction and precision engineering ensure consistent performance and durability, making it suitable for heavy-duty applications where reliability is paramount.
Installation of this manifold requires attention to proper torque specifications and alignment, as outlined by the manufacturer. Regular maintenance and inspection will enhance longevity, especially in high-thermal environments typical of towing and fleet operations. This product is not CARB-approved and is intended for off-road or replacement use only. It is crucial to verify compatibility with your vehicle’s specific engine configuration before installation to ensure optimal performance and fitment.
Features:
- Heavy-duty construction from high-silicon ductile iron to prevent warping and cracking
- Extended fasteners and spacers (15mm longer) to reduce bolt stress and prevent failures
- Includes all new bolts, spacers, and gaskets for complete replacement
- Designed to fit 2002-2013 GM LS truck engines with OEM replacement quality
