ARP Main Stud Kit for Toyota 4AG 16V #203-5403

ARP Main Studs

There are many important reasons to use ARP main stud kits,
including the elimination of main cap walk and fretting, as well as protecting
the threads in your engine block. All kits come complete with hardened
parallel-ground washers and high-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 200,000 psi tensile strength, and precision J-form threads rolled
after heat treat to create a fastener that has threads 1000% stronger than
others.
