Don't reuse the old, corroded bolts when installing a new exhaust manifold on your 1989-2017 Dodge 5.9/6.7L Cummins, replace them with the Exhaust Manifold Installation Bolt Kit . This kit includes (12) stainless steel allen head bolts and (12) stainless steel lock washers so you can install your new aftermarket exhaust manifold, with brand new hardware.
Note: This kit is intended for use on aftermarket exhaust manifolds and will not work with the stock manifold, or with the stock spacers. Due to different model years, and configurations, there are some instances where the factory supplied hardware is re-used and may take place of a bolt. In those situations, not all the bolts within this kit will be needed.
