- Exceptional Strength: Each stud is made from 8740 chromoly steel, a high-strength alloy heat-treated for a tensile strength of 190,000 psi, providing a massive increase in strength over stock bolts.
- Precision Manufacturing: The studs are cold-forged and then thread-rolled after heat-treat, a costly but crucial process that significantly boosts their fatigue strength and ensures perfect thread engagement for an even clamping force.
- Complete Kit: This comprehensive kit includes hardened parallel-ground washers and hex nuts, which guarantee accurate torque readings and proper load distribution.
- Optimized for Cummins: Specifically designed for the 2007-2018 Dodge Ram 6.7L Cummins engine, ensuring a perfect fit and dependable performance.

The ARP 230-4202 head stud kit is an essential upgrade for any owner of a 2007-2018 Dodge Ram with a 6.7L Cummins engine. When you're pushing your diesel to its limits—whether for towing, performance tuning, or competition—factory head bolts are a weak point. They can stretch under high cylinder pressure, leading to a catastrophic and expensive head gasket failure. The ARP 230-4202 studs are specifically engineered to provide a uniform and superior clamping force, ensuring your cylinder heads stay securely in place. Manufactured from a premium 8740 chromoly steel, these studs are heat-treated to an impressive tensile strength of 190,000 psi, offering a level of reliability and durability that factory hardware simply cannot match.
