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.
When you are building a high-horsepower Cummins engine, standard studs may not be enough. The ARP 247-4204 CA625+ Head Stud Kit is engineered for the most demanding applications, offering significantly higher tensile strength than standard 8740 chromoly studs. Designed for 1998 and newer 5.9L and 6.7L 24V Cummins engines, this kit is the ultimate insurance policy for your high-boost, high-torque build.
If you are running a large compound turbo setup or high-pressure injectors, you cannot afford to compromise on head hardware. The CA625+ material provides the ultimate in clamping force, ensuring your head gasket stays put under the most intense conditions. This kit includes all necessary hardware to upgrade your engine to the highest level of reliability. Invest in the best, and give your Cummins the strength it deserves. Find all your high-performance diesel upgrades at GGCRACING.
