ARP Head Stud Kit, Toyota 2JZ

Upgrade the performance of your Toyota 2JZ engine with an ARP Head Stud Kit. Specifically designed for the turbocharged inline 6-cylinder 2JZ engines found in high-performance models such as the MKIV Supra and Lexus GS300. As you increase the power output of your engine beyond its factory specifications, the head and block may start to separate, causing factory bolts to stretch and fail. Our ARP Head Studs are designed to be stronger than factory bolts, ensuring your race engine stays together even under extreme conditions. The ARP Custom Age 625+ kit is made from a material with a tensile strength of 260 ksi, substantially higher than the 190 ksi of the ARP 2000 head stud. It's an ideal choice for individuals who want to push the limits of their 2JZ builds. Installation Instructions:  1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser. 2. Clean and inspect all hardware prior to installation.
