ARP Head Studs - 2ZZ
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. Overkill? Probably. But you know they’re the best.
