BD Diesel Exhaust Manifold Bolt and Spacer Kit - Dodge 1998.5-2018 5.9L/6.7L Cummins

When you're working on the exhaust manifold of your 1998.5-2018 Dodge 5.9L or 6.7L Cummins, using the right hardware is key to a lasting repair. Many aftermarket bolts are shorter than stock, and after repeated heating and cooling cycles, they can stretch and lead to exhaust leaks or even break. This kit from BD Diesel addresses those issues directly with stronger, longer bolts and specialized spacers.

This kit features Class 10.9 flanged head bolts, which offer a good balance of strength and toughness to handle the stresses of the exhaust system. Unlike some bolts that can suffer from zinc embrittlement due to their plating, these fasteners are non-zinc plated. The included black oxide spacers are designed to help the bolts operate within their elastic stretch range, preventing fracture or permanent yield, and the black oxide coating on the spacers matches BD manifolds. You also get stainless steel socket bolts and washers for added durability.

Replacing worn or damaged exhaust manifold bolts is a smart move to ensure a solid seal and prevent future headaches. This kit gives you the necessary hardware to get the job done right.
