This ARP main stud kit replaces the factory main cap bolts on the Ford 2.0L Pinto inline-4 with high-strength chromoly studs and nuts for more consistent clamping load on the crankshaft main caps. Studs allow the caps to be torqued more accurately and repeatably than bolts, which improves main-bearing retention during performance or rebuild work. Fits 2-bolt main blocks.
