ARP 151-5404 Main Stud Kit for Ford 2.0L Zetec

ARP's 151-5404 Main Stud Kit delivers competition-grade reliability for your Ford 2.0L Zetec engine. Forged from 8740 chrome moly steel and heat-treated to 200,000 psi tensile strength, these studs eliminate main cap walk and fretting while protecting your block's threads. The precision J-form threads are rolled after heat-treat, delivering approximately 1000 times greater fatigue resistance than conventionally threaded fasteners. Each kit includes hardened parallel-ground washers and premium nuts, with specialized standoff studs and serrated lock nuts for secure windage tray mounting where applicable. Purpose-built for serious engine builders demanding uncompromising performance and durability.
