ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
The Toyota JZ-Series engine is world-renowned for its ability to handle massive power, but that power requires a rock-solid foundation. The ARP Main Stud Kit is designed to provide the ultimate clamping force for your 2-bolt main JZ engine. By utilizing these high-strength chromoly studs, you significantly reduce the risk of main cap movement, ensuring your crankshaft remains perfectly aligned even under the most demanding racing conditions.
Unlike standard bolts, studs provide a more stable clamping force and prevent the threads in your block from wearing out during routine maintenance. This kit is a must-have for any high-boost or high-RPM JZ build, providing the structural integrity needed to push your engine to its limits. The 12-point nuts are designed for high-torque applications, ensuring that your main caps stay exactly where they belong. Every component in this kit is manufactured to the highest standards, reflecting the quality that enthusiasts expect from ARP. Don't compromise on the heart of your engine; secure your JZ-Series rotating assembly with the best hardware available at GGCRACING.
