Ring Gear Bolt Kit fits Chrysler 7-1/4" & 8-3/4" Diff (1972 & Earlier) .390" Grip

The tremendous shock loads generated at launch by most any drag racing vehicle equipped with today's sticky tire compounds or the acceleration and deceleration of oval track cars put considerable strain on the ring gear. For this reason, the fastener experts at ARP have developed the Pro Series ring gear bolts. They're forged from premium grade 8740 chrome moly steel and are heat-treated to a nominal rating of 190,000 psi tensile strength. Specially hardened, precision-ground washers are included where required. Available to fit most any ring gear setup ranging from popular 9" Ford GM 10- & 12-bolt rear ends to the beefy Strange differentials found in Top Fuel and Funny Car applications.
