Pro Series Ring Gear Bolt Kit

The ARP 4216-3AK is a ring gear bolt kit designed for differential cases. This kit includes ten bolts, each measuring 7/16-20 x 15/16, along with hardened, precision-ground washers. Built with ARP's Pro Series quality, these bolts are forged from 8740 chrome moly steel and heat-treated to a tensile strength of 200,000 psi.

Featuring a 12-point socket head and a 1/2 shank, this kit is engineered to withstand the tremendous shock loads generated in drag racing and oval track applications. The manufacturer recommends careful installation, including proper torqueing in an alternating or crossing pattern, and checking tightness routinely, especially in high-stress scenarios like tire shake.
