This stud kit is designed for the Toyota 1ZZ-FE, 2ZR-FE, 2ZR-FAE, 1ZR-FE, and 1ZR-FAE engines. It provides superior clamping for the cylinder head, improving head gasket sealing. Unlike the stock head bolts, these studs are also reusable.
Kit includes 10 studs, 10 12-point nuts, 10 washers, ARP assembly lube,
The studs in this kit are made of ARP’s proprietary ARP2000 material. Boasting 220,000psi tensile strength these are simply the strongest head studs you can buy anywhere for the 2ZZ/1ZZ. Overkill? Probably. But you know they’re the best.
Torque Spec:
65 ft-lb with ARP lube
Torque only to the spec above; do NOT turn an additional 90 degrees.
