1967-92 Camaro Small Block Harmonic Balancer Bolt Kit. As the crankshaft flexes and twists, the damper absorbs incredible amounts of kinetic energy. To ensure that the damper is locked in position, ARP has developed these ultra strong 190,000 psi bolts that let you exert maximum clamping force. Special features include 1/4" thick, wide area washer and an extra tall 5/8 12-point head that accepts a deep socket and eliminates the worry of stripping the head. Will not fit big block, Pontiac, LS or V6 engines - small block Chevrolet V8 only. 2.470 Underhead Length with 7/16-20 threads

Product includes: Bolt, washer and fastener assembly lubricant
