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.
Secure your engine block with the Auto Racing Products (ARP) Main Stud Kit, specifically engineered for Mitsubishi 4-cylinder engines with 2-bolt mains. When building a high-horsepower engine, the main cap fasteners are critical for preventing block distortion and ensuring bearing longevity. These 12-point studs are manufactured from premium chromoly steel and finished with a black oxide coating for maximum corrosion resistance and durability.
Using studs instead of bolts provides a more accurate and consistent clamping force, which is essential for high-compression or turbocharged builds. The 12-point nut design allows for easier access in tight engine bays and provides a higher torque capacity than standard hex nuts. By upgrading to this ARP kit, you are investing in the long-term health of your crankshaft and main bearings, reducing the risk of catastrophic engine failure under extreme stress. Whether you are building a street machine or a dedicated track weapon, GGCRACING offers the professional-grade fasteners required to keep your engine together under pressure.
