As the crankshaft flexes, the balancer absorbs incredible amounts of energy. ARP balancer bolt kits will ensure that your balancer is locked into position. They feature a 12-point head that accepts a deep socket to eliminate the fear of stripping the head.

Answer This Question


If I use the ARP bolt with the GM crank bolt washer, will that work with my ATI Damper on my Caprice PPV L77 LS based motor?

Asked by DAKODA on November 18, 2019


Yes it will, but I used the washer provided with this product on my 383 stroker build for my ls1 engine and its worked perfect currently pushing 767whp.
