Specialty brass flat washers (custom size, 3/8″) for water pump and accessory drive bolts – set of 4. These 3/8” brass specialty washers are slightly thicker, and have a smaller outer diameter than standard 3/8” washers. They are closer to the OEM washers that were installed on the Atomic 4. The thicker size improves the sealing qualities of the washer, and the smaller outer diameter will fit the accessory drive block recess.
