5.9L/6.7L 1998.5+ Cummins ARP Head Stud Kit (247-4202)

Keep your Cummins sealed under boost and heavy load with the ARP 247-4202 Head Stud Kit for 1998.5+ 5.9L and 6.7L 24-valve engines. Designed for high cylinder pressures from towing, performance tuning, and upgraded turbo setups, these premium studs deliver far more consistent and reliable clamping force than factory torque-to-yield head bolts—helping prevent head lift and blown head gaskets.

Manufactured to ARP’s exacting standards and heat-treated for strength and durability, this kit is a go-to upgrade for stock to high-horsepower builds where sealing and long-term reliability matter most.
