The ARP 3/8 ID x .720 OD black washer kit includes washers sized for 3/8-inch fasteners with a .720-inch outer diameter finished in black. These washers provide a specific dimensional fit where assemblies require a 3/8 ID and .720 OD washer, offering a direct replacement option for maintenance and rebuilds that call for those measurements and a low-profile black appearance.
