ARP 8740 Chromoly Main Stud Kit - Saturn 1.9L DOHC (1991-1999)

This ARP main stud kit replaces the factory main cap hardware on the Saturn 1.9L DOHC engine, securing the main caps with 8740 chromoly studs heat-treated to 190,000 psi tensile strength. Studs deliver more consistent clamp load than factory bolts, holding crankshaft alignment during rebuilds and higher-stress builds. Threads are rolled after heat-treat for maximum strength.
