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 bottom end of your Jeep 4.0L Inline-6 is the foundation of your engine's power. Protect it with the Auto Racing Products Main Stud Kit. Designed for 2-bolt main configurations, these studs offer significantly more stability than OEM main bolts, reducing main cap walk and ensuring your crankshaft remains perfectly aligned under high RPM and heavy load conditions.
Main studs are an essential upgrade for any performance-oriented build. Unlike bolts, which can twist and stress the block threads during installation, studs are installed finger-tight, allowing for a more accurate and even torque distribution. This ensures that the main caps are held firmly in place, extending the life of your bearings and crankshaft. Whether you are building a daily driver that sees occasional off-road abuse or a dedicated racing engine, this kit provides the necessary structural integrity to keep your engine running smoothly. GGCRACING is your source for premium engine fasteners that deliver professional results every time.
