The Toyota Main Stud Kit - 22R by ARP is designed specifically for engine builders and dedicated Toyota enthusiasts who require dependable performance under high-stress conditions.

Each stud is individually finished and validated to ARP's stringent quality standards, ensuring straightness and thread integrity right out of the box.
