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 Mopar Gen III 5.7L or 6.1L Hemi is subject to immense stress during high-performance operation. The Auto Racing Products (ARP) Main Stud Kit is engineered to keep your main caps locked in place, preventing cap walk and ensuring the integrity of your crankshaft bearings. These studs provide a more stable foundation for your rotating assembly compared to factory main bolts.
Using studs instead of bolts allows for more consistent torque values, as the studs do not undergo the same torsional stress during installation as bolts do. This results in a more uniform clamping load on the main caps, which is essential for high-RPM stability and long-term engine health. The black oxide finish ensures that these studs remain protected against corrosion, even in harsh racing environments. Whether you are building a street-driven performance engine or a dedicated track-only Hemi, this kit is an essential component for a reliable bottom end. Upgrade your engine's foundation with professional-grade parts from GGCRACING.
