Elevate the durability and performance of your Dodge/Ram Cummins engine with the Gator HD220 Head Stud Kit. Engineered from HD220 alloy, these head studs provide an exceptional 220,000 PSI tensile strength and a load rating in excess of 120 kN, ensuring reliable cylinder-head clamping under the most demanding boost and thermal conditions.
Key Features:
-
HD220 Alloy — 220,000 PSI Strength: Industry-leading tensile strength. Holds tight under extreme boost and heat.
-
Precision-Machined & Rolled Threads: Threads are cold-rolled after heat treatment for maximum fatigue resistance and long-term durability.

Why Upgrade Your Stock Head Bolts?
Factory head bolts are prone to stretch under high boost, leading to blown head gaskets, lost compression and costly downtime. The Gator HD220 Head Studs eliminate this weak link with superior, consistent clamping force whether you’re daily driving, towing heavy loads or chasing big horsepower numbers.
