ARP head stud kit for ZR & ZZ Engines
This stud kit has been meticulously crafted for use with Toyota for 1ZR/2ZR & 1ZZ/2ZZ engines. It is engineered to deliver superior clamping force for the cylinder head, thereby enhancing the sealing of the head gasket. Unlike the stock head bolts, these studs are reusable, adding to their value and longevity.
The kit comprises 10 studs, 10 12-point nuts, 10 washers, ARP assembly lube, and comprehensive assembly instructions provided by MWR.
Crafted from ARP's exclusive ARP2000 material, these studs exhibit an impressive tensile strength of 220,000 psi, making them the epitome of strength and durability for the 1ZR/2ZR & 1ZZ/2ZZ engines. While their strength may be considered excessive for some applications, they undeniably stand as the premium choice for discerning enthusiasts.
