ARP water pump pulley stud kits offer a reliable solution for installing fan spacers that are employed to facilitate the removal of clutch fans—or simply position a direct drive fan closer to the radiator for optimum cooling. ARP delivers a variety of stud kits ranging in overall lengths from 1.250 in. to 4.500 in. Also, the kits are available in polished stainless steel or black oxide finished 8740 chromoly, with either hex or 12-point nuts, and all include washers. ARP water pump pulley studs are nominally rated at 170,000 psi tensile strength and far superior to even Grade 8 hardware, which is an important safety consideration for securing a fast-spinning fan. Choose the length needed for your application.
