This stud kit is specifically designed for the Toyota 1ZZ-FE or 2ZR-FE engine, providing superior clamping force to the engine cylinder head, and superior head gasket sealing as a result. These studs are also re-usable, unlike the factory equivalent part.
Produced from ARPās proprietary ARP2000 material, these parts exceed standards with 220,000 psi tensile strength, making themĀ the strongest head studs you can buy.
