Head Bolt Washer KitFor ARP Head Bolts Sold as a Kit
A head bolt without the correct washer can gall the aluminum casting under torque or fail to spread clamping load evenly across the head, which shows up later as a leaking gasket. This washer kit is sized specifically for ARP head bolts so clamping load transfers into the head the way it was engineered to.
