ARP 3/4 ID x 1.75 OD Chamfered Black Washer, each

Brand: Automotive Racing Products (ARP)

These hardened, parallel-ground 3/4" ID chrome moly washers are ideal for distributing a compression load over more surface area than standard washers.

The 1 3/4" OD is larger than the 1 5/164" OD of a standard AN960-1216 washer. The 0.275" thickness is also more than 4 times as thick as a standard AN960-1216. The ID is chamfered on one side to accomodate a radius under your bolt head (the other side is flat). Black oxide finish. Sold individually.
