This stud kit is specifically designed for the Toyota 2ZR-FE engines. This kit provides far superior clamping for the cylinder head, improving head gasket sealing. Studs are ARP Pro Series made of 8740 alloy, with 200,000 psi yield strength. Threads are rolled before heat treat, dramatically improving durability. These studs are also re-usable, unlike the torque-to-yield stock head bolts.
Kit includes 10 studs, 10 12-point nuts, 10 washers, ARP assembly lube, and assembly instructions.
