Camshaft positioning is critical on DOHC overhead cam engines, especially so on upgraded high performance engines with aggressive cam profiles. ARP ensures that your cam towers are properly secured using these durable studs. Far superior to OE fasteners, these studs are made from 8740 chromemoly steel with threads rolled after heat-treatment which gives them about 1000% better fatigue strength than those studs that are threaded prior to heat-treatment.
