Product Description

The BD Diesel 1045982 Exhaust Manifold Bolt & Spacer Kit is a comprehensive hardware solution engineered for diesel truck applications using Cummins 5.9L and 6.7L engines from 1998.5 through 2018. Designed to replace worn, stretched, or corroded fasteners, this kit features high-strength Grade 10.9 bolts and black oxide spacers that resist the extreme heat cycles common in exhaust systems, helping reduce the risk of bolt fatigue and failure over time.

Each bolt and spacer in this kit is configured to provide proper clamping force and thermal durability when installing aftermarket or replacement exhaust manifolds. The included stainless steel socket head bolts and washers make it easier to access hard-to-reach mounting points, while the black oxide coating on the spacers matches manifold finishes and resists corrosion. Whether refreshing worn hardware during a manifold replacement or upgrading to more durable components, this kit offers a direct-fit solution for heavy-duty Cummins diesel exhaust installations.
