When building or rebuilding your Nissan L-series engine, the integrity of your bottom end is paramount. The ARP Nissan L20 Main Stud Kit (202-5401) provides the superior clamping force required to keep your main caps locked in place under high-performance conditions. Unlike standard factory bolts, these studs are manufactured from premium 8740 chromoly steel, heat-treated to ensure consistent tensile strength and fatigue resistance.

Why Choose ARP Main Studs?

They ensure that your crankshaft remains stable, even under heavy load or high-RPM operation. This kit is specifically designed to fit a wide range of Nissan vehicles from the 1974-1980 era, including the 200SX, 510, 610, 620, 710, and 720 models.
