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 5.9L 12V Cummins is legendary for its durability, but when you start adding performance upgrades, the factory fasteners can become a weak point. This ARP Main Stud Kit is the industry standard for securing main caps in high-output 12V Cummins builds. By utilizing high-strength chromoly steel, these studs provide the consistent clamping force needed to keep your engine internals stable under extreme cylinder pressures.
When you are pushing your 12V Cummins to the limit, you need components that won't fail. These main studs are heat-treated and precision-machined to ensure they meet the rigorous demands of competitive diesel pulling, drag racing, or heavy-duty towing. Unlike standard bolts, studs provide a more accurate torque reading because they do not twist during installation. This ensures that the clamping load is evenly distributed across the main caps, promoting longer bearing life and overall engine longevity. Ensure your build is ready for the road or the track with top-tier hardware from GGCRACING.
