Description

The ARP 100-3212 is a water pump pulley stud kit designed for installing fan spacers. These studs facilitate the removal of clutch fans or allow a direct drive fan to be positioned closer to the radiator for improved cooling. The kit includes four 5/16-24 x 3.750-inch studs made from black oxide finished 8740 chromoly.

These studs are rated at 170,000 psi tensile strength, offering superior performance compared to Grade 8 hardware. The kit is designed to fit a 2.500-inch fan spacer and includes hex nuts and washers.
