BD DIESEL 1045982 5.9L/6.7L CUMMINS EXHAUST MANIFOLD BOLT AND SPACER KIT – DODGE RAM 1998.5–2018

Product Description

The BD DIESEL 1045982 Exhaust Manifold Bolt and Spacer Kit is the best upgrade for replacing broken, stretched, or corrosion-prone factory exhaust manifold hardware on 1998.5–2018 Dodge Ram 5.9L and 6.7L Cummins engines. Exhaust leaks, ticking sounds, and repeated re-torquing are often caused by fatigued bolts and weak hardware. This kit is engineered to improve clamping strength and maintain a reliable seal through extreme heat cycles.

BD Diesel 1045982 exhaust manifold bolt kit, Cummins manifold hardware, 5.9L Cummins exhaust bolts, 6.7L Cummins exhaust bolts, manifold spacer kit, grade 10.9 bolts, black oxide spacers, exhaust leak repair kit

BD Diesel includes Grade 10.9 flange-head bolts for the ideal balance of strength and elasticity, along with black oxide coated exhaust spacers that allow the fasteners to operate in elastic stretch without fracture or permanent yield. Non-zinc plated fasteners help prevent zinc embrittlement, making this kit an excellent long-term fix for common Cummins manifold hardware failures.

Will this kit work with a stock exhaust manifold?

Yes. This bolt and spacer kit is designed to work with stock exhaust manifolds as well as BD Diesel aftermarket manifolds.

Why are spacers included?

The spacers help the bolts operate in elastic stretch through heat cycles, reducing fatigue and helping prevent bolt breakage and exhaust leaks over time.

Do 2003–2007 trucks require any extra steps?

Yes. 2003–2007 5.9L Cummins applications may require removal of the factory heat shield during installation.
