This stud kit is specifically designed for the Toyota 1ZZ-FE or 2ZR-FE engine (works in all make and model years powered by 1ZZ/2ZR engine). It provides superior clamping for the cylinder head, improving head gasket sealing. These studs are also re-usable, unlike the stock head bolts.

The studs in this kit are made of ARP’s proprietary ARP2000 material. Boasting 220,000 psi tensile strength these are simply the strongest head studs you can buy anywhere for the 2ZZ. Overkill? Probably. But you know they’re the best.
