ARP Special Purpose Washers

If you need washers in a thickness or OD that isn't available elsewhere, ARP Special-Purpose Washers may have what you need!

These hardened, parallel-ground chrome moly washers are available with a variety of ID, OD, and thickness combinations that don't stick to the strict sizing of AN hardware. If you don't see the size you need here, let us know!

We also offer ARP Insert Washers which have a special snout that protects the hole from galling or collapsing!
