Engineered to solve chronic head gasket failures in Ford's 6.4L Power Stroke, the Gator Fasteners HD220 Head Stud Kit (HSK64) replaces weak factory bolts with high-strength HD220 alloy.

This proprietary material delivers 220,000 PSI tensile strength - surpassing 8740 chromoly - to handle extreme cylinder pressures from upgraded turbos and tuning modules.

Each stud features precision-rolled threads after heat treatment, preserving grain structure for maximum fatigue resistance. The black oxide finish provides corrosion protection in harsh environments, while the included Gator Juice assembly lube and 12-point heavy duty nuts ensure accurate torque application and clamp load during installation.

Vehicle Compatibility: Fits 2008-2010 Ford F-250, F-350, F-450, and F-550 Super Duty trucks with 6.4L Power Stroke engines. Follow included torque sequences for optimal results.
