Upgrade tired, rusty or mismatched exhaust fasteners with this ARP exhaust/header manifold bolt set. Designed for Chrysler, Dodge, Plymouth and Valiant small block V8 applications using 5/16-18 exhaust bolts, these black oxide chromoly fasteners are a neat and stronger alternative to generic hardware.

The compact 6-point hex head is well suited to tight access around extractors, header pipes and factory-style manifolds, helping make installation and future servicing easier in a crowded engine bay. A great choice for restorations, exhaust upgrades or freshening up a classic Mopar engine with quality fasteners that look tidy and do the job properly. Always confirm thread size and bolt length against your engine and manifold or header flange before fitting.
