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 legendary 12-valve 5.9L Cummins is known for its durability, but when you start adding performance modifications, the factory main bolts reach their limit. This ARP Main Stud Kit is specifically engineered for 1989-1997 Dodge 5.9L Cummins engines with a 2-bolt main setup. These studs provide the superior clamping force needed to keep your main caps locked in place, even under heavy load and high boost conditions.
Installing this kit is a critical step in any high-performance build or engine overhaul. Because studs do not exert the same torsional stress on the block threads as bolts, they provide a more accurate and consistent torque reading. This ensures your crankshaft remains properly supported, extending the life of your bearings and block. Whether you are building a reliable work truck or a high-horsepower drag machine, this ARP kit is the foundation for a solid bottom end. Trust the experts at GGCRACING to provide the high-quality fasteners your Cummins deserves.
