The ARP main stud kit is specified for small-block Chevy WP Motown iron blocks and provides a heavy-duty fastener solution for securing main caps. Offered as a hardware package for engine builders, it replaces factory bolts with higher-strength studs intended to increase clamp reliability. Use this kit when assembling or upgrading the bottom end to improve main-cap retention and achieve a more serviceable and robust main fastening setup in supported SB Chevy iron-block applications.
