Product Description

The ARP AMC 343-401 Hex Head Main Stud Kit is engineered to provide superior clamping force for the main caps of AMC 343, 360, 390, and 401 cubic inch engines from 1970 and newer. These main studs are precision-machined from premium ARP2000 material, offering significantly increased tensile strength over factory bolts. Using main studs helps prevent cap walk and fretting, which is crucial for high-performance and racing engine builds.
