ARP Head Studs - 1ZZ
This stud kit is specifically designed for the Toyota 1ZZ-FE and 2ZR-FE engines. It provides superior clamping for the cylinder head, improving head gasket sealing. These studs are also re-usable, unlike the stock head bolts.
Kit includes 10 studs, 10 12-point nuts, 10 washers, ARP assembly lube, and MWR assembly instructions.
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.
