BD DIESEL 1041400 EXHAUST MANIFOLD KIT SILVERADO/SIERRA 1500 V8 2002–2013

Product Description

The BD DIESEL 1041400 Exhaust Manifold Kit is a heavy-duty replacement solution for cracked manifolds, leaks, and broken manifold bolts on 2002–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 V8 LS-based engines. This kit is engineered to fix one of the most common GM exhaust issues: heat-cycling that causes warping, bolt stress, and manifold cracking. BD’s upgraded design features a thicker, stronger casting and improved mounting strategy to help prevent repeat failures and keep your truck running quiet, strong, and leak-free.

BD Diesel 1041400 exhaust manifold kit, Silverado 1500 exhaust manifold replacement, Sierra 1500 exhaust manifold kit, GM LS cracked manifold fix, broken manifold bolt repair kit, high silicon ductile iron manifold, thick wall manifold, longer manifold bolts spacers gaskets

Built from high-silicon ductile iron, these manifolds provide increased strength and heat resistance to reduce warping over time. The kit includes new longer bolts and spacers to reduce fastener stress during thermal expansion, along with new gaskets for a complete repair. Machined bolt mating surfaces improve sealing and help ensure a secure, long-lasting installation.

Does this kit include gaskets and hardware?

Yes. This kit includes new gaskets, longer bolts, and spacers for a complete installation.

Why are the bolts and spacers longer than stock?

The longer bolts and spacers reduce fastener stress caused by thermal expansion, helping prevent broken bolts and repeat manifold failure.

Is this kit designed to prevent manifold cracking?

Yes. The thicker casting and high-silicon ductile iron construction are designed to improve durability and reduce cracking compared to OE manifolds.
