This ARP broached main stud is specified for Ford 4.6L V8 applications and is supplied as a single replacement hardware piece. The 1.25 x 1.5-inch stud is intended for inner main installation where a precision broached stud is required to secure rotating assemblies. Use it as a direct replacement when rebuilding or servicing the crankshaft/upper main area to restore factory-style clamping where a single stud is specified.
