Boost the reliability and strength of your Dodge/Ram Cummins engine with the Gator HD220 Head Stud Kit. Made from Gator’s proprietary HD220 alloy, these studs offer a powerful 220,000 PSI tensile strength and over 120 kN of clamping force—ideal for keeping your cylinder heads sealed during extreme boost, heat, and performance demands.

Key Features:

• HD220 Alloy — 220,000 PSI Strength: Delivers class-leading tensile strength to hold firm under intense pressure and thermal loads.

• Cold-Rolled Threads: Rolled after heat treatment to preserve structural integrity and enhance fatigue resistance for long-term performance.

Why Upgrade from Factory Head Bolts?
