ARP Custom Age 625+ Pro Series Head Stud Kit - Toyota Supra 2JZ-GTE (Ultimate Strength)
When pushing the limits of the Toyota 2JZ-GTE engine beyond the 1000+ horsepower mark, only the best will suffice. Straight Six Imports proudly offers the ARP Custom Age 625+ Pro Series Head Stud Kit, the ultimate head-sealing solution for your Toyota Supra (MKIV) 2JZ-GTE engine.
The Custom Age 625+ material is ARP's proprietary super-alloy, boasting a nominal tensile strength of 260,000 psi—significantly higher than the standard ARP2000 material. This extreme strength is essential for handling astronomical cylinder pressures generated by large turbochargers and high-boost levels. This kit guarantees the highest achievable clamping force, eliminating any possibility of cylinder head lift and subsequent head gasket failure.
