- Unmatched Strength: The studs are made from ARP 2000, a high-strength alloy heat-treated to 220,000 psi, far exceeding the strength of OEM hardware.
- Precision and Reliability: The studs are centerless ground and thread-rolled after heat-treat, a process that dramatically increases fatigue strength and ensures a perfect, uniform clamping force.
- Complete Kit: This professional-grade kit includes hardened parallel-ground washers and hex nuts, designed to provide accurate torque readings and even load distribution across the cylinder head.
- Superior Corrosion Resistance: Finished with a black oxide coating, these studs are built to resist corrosion and last for the life of your engine.

When you're pushing your 2007-2018 Dodge Ram 6.7L Cummins to the limit, the factory head bolts are a weak link. High cylinder pressures from performance tuning, towing heavy loads, or competition can cause stock bolts to stretch, leading to a loss of clamping force and a blown head gasket. The ARP 230-6301 head stud kit is the ultimate solution, providing the peace of mind and bulletproof reliability you need. These studs deliver a consistent and superior clamping force, effectively locking your cylinder heads in place to prevent head gasket failure. Each stud is manufactured from a premium ARP 2000 alloy and is heat-treated to an incredible tensile strength of 220,000 psi. This isn't just a replacement part; it's an essential, proactive upgrade to protect your investment.
