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.
When building a high-horsepower 94-Up Mitsubishi 4G63 engine, compromise is not an option. The Auto Racing Products (ARP) Custom Age 625+ Cylinder Head Stud Kit represents the pinnacle of fastener technology, engineered to provide unparalleled clamping force and resistance to stretching. This kit is absolutely essential for extreme performance applications, ensuring your cylinder head remains perfectly sealed even under the most brutal boost pressures and RPMs.
What sets this kit apart is the use of ARP's proprietary Custom Age 625+ material. This super-alloy boasts a tensile strength significantly higher than standard chromoly, making it the strongest fastener material available from ARP. Each 11mm stud is meticulously heat-treated and precision-ground, then finished with a black oxide coating for enhanced corrosion resistance and a professional appearance. The kit includes 12-point nuts, allowing for precise and consistent torque application, which is critical for maintaining head gasket integrity in demanding 4G63 builds.
The Custom Age 625+ material is specifically developed for applications where standard materials simply won't hold up. Its superior fatigue life and resistance to elongation mean your head gasket will stay sealed, preventing costly engine damage and ensuring consistent power delivery. For serious drag racers, road racers, and high-boost street cars, this ARP kit is the ultimate investment in engine reliability and performance. Trust GGCRACING.COM for the most advanced fasteners for your Mitsubishi 4G63 build.
