Product Description

The ARP 202-5401 Main Stud Kit is engineered specifically for the Nissan/Datsun L20 Series engines with a 2-bolt main configuration. This kit is essential for those seeking to enhance engine reliability and performance, particularly in high-stress environments such as racing or performance builds.

Constructed from ARP 8740 chrome moly steel and heat-treated to a tensile strength of 200,000 psi, these studs offer exceptional strength and durability. The precision J-form threads, rolled after heat treatment, ensure superior thread integrity and resistance to stretching under high loads. The kit includes hardened parallel-ground washers and high-quality nuts, providing a secure and consistent fastening solution.

By replacing the factory bolts with ARP studs, you eliminate issues like main cap walk and thread fretting, which can lead to engine failure. This upgrade is a critical step in building a robust and reliable engine capable of handling increased power and torque.
