ARP Main Studs MazdaSpeed3 2007-2013


ARP 03 Mazda 2.3L DOHC 16V Main Stud Kit


There are many important reasons to use ARP main stud kits for your 2.3L MS3, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block. Every ARP main stud kit exceeds the most stringent aerospace specifications. All kits come complete with hardened parallel-ground washers and aerospace quality nuts. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely in place. The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.
