The ARP insert washer features a .875" outer diameter with a 7/16" inner diameter and is sold as a 2-pack. Intended as an insert-style washer, it provides controlled spacing and a defined bore for fastener alignment in assemblies that require a larger OD with a 7/16" shaft. Include these in repair or build tasks where matching ID/OD sizing ensures consistent fit and clamping.
