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.
Ensure your 5.9L 12V Cummins engine stays sealed under extreme boost and high-performance conditions with the Auto Racing Products (ARP) 247-4203 Head Stud Kit. Designed specifically for the legendary 12-valve Cummins platform, this kit is the industry standard for preventing head gasket failure in modified engines.
Each stud is cold-forged and heat-treated to provide superior tensile strength compared to factory bolts. The 12-point nuts allow for easier access in tight engine bays, ensuring you can achieve accurate clamping force every time. Whether you are building a street-strip truck or a dedicated tow rig, these studs provide the clamping force necessary to keep your cylinder head locked down under high cylinder pressures.
Don't risk a blown head gasket during your next pull or race. Invest in the best engine hardware available for your diesel build. Experience the professional-grade quality of ARP components available at GGCRACING.
