About This Item

Automotive Racing Products (commonly known as ARP) has been around since 1968 producing studs and bolts to meet the demands of racing enthusiasts.

The ARP Main Stud Kit for the 4-cylinder SOHC 16-Valve 1.5-liter L15/LEA engines commonly found in the Honda CR-Z and Fit is a set of high performance block main studs and nuts. Using a high quality 8740 Alloy Chrome Moly steel, these bolts have a tensile strength within the 190,000 PSI range and made with the strictest of tolerances for easy installation. ARP Main studs ensures elimination of main cap walk and fretting for high power builds.

If you are rebuilding your motor or plan on upgrading your internals this is a must for any race or performance application!
