- Unmatched Strength: The studs are crafted from ARP 2000 material, a high-strength alloy with a tensile strength of 220,000 psi, which is far superior to OEM hardware.
- Precision and Reliability: Each stud is centerless ground and thread-rolled after heat-treat. This specialized process dramatically increases fatigue strength and ensures a perfect, uniform clamping force for a leak-free seal.
- Complete Kit: This comprehensive kit includes hardened parallel-ground washers and hex nuts, designed to provide accurate torque readings and proper load distribution across the cylinder head.
- Superior Corrosion Resistance: A durable black oxide coating on the studs provides excellent corrosion resistance, ensuring long-term durability and protection.

The ARP 230-6302 head stud kit is a crucial upgrade for anyone with a 2007-2018 Dodge Ram 6.7L Cummins diesel engine. While the Cummins is a legendary workhorse, factory head bolts are a common weak point when pushing the engine beyond stock power levels. High cylinder pressures from performance tuning, towing heavy loads, or competition can cause the factory bolts to stretch, resulting in a loss of clamping force and a catastrophic head gasket failure. The ARP 230-6302 kit provides a superior solution by delivering a consistent, powerful clamping force that locks your cylinder heads in place, effectively preventing this type of failure. Manufactured from a premium ARP 2000 alloy, these studs are heat-treated to an incredible tensile strength of 220,000 psi. This kit is not just a replacement; it's a vital, proactive investment in your engine's longevity and performance.
