ARP 1352503 Square Drive Balancer Bolt

To maintain a reputation for "zero defects", ensure optimum quality control, and produce fasteners of exceptionally high quality, ARP controls all aspects of the manufacturing process, performing all operations in-house where they can be closely monitored. This square drive balancer bolt is a good example of how ARP takes extraordinary steps to produce the very finest products of their kind on the market today. As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy, so ARP has developed these ultra strong 200,000 psi bolts that let you exert maximum clamping force to ensure that the balancer is locked in position. Manufactured from heat-treated 8740 chrome moly steel with heavy-duty black oxide finish, the bolt comes complete with a 1/4" thick, wide area washer. The feature that sets this bolt apart from ARP's other harmonic balancer bolts is the head, which can accept a standard 1/2" drive ratchet or breaker bar to facilitate rotating the crank assembly.
