Gator Fasteners HSK67F HD Head Stud Kit 11-21 Ford F250/F350 Super Duty 6.7L

Engineered to solve head gasket failures in Ford's 6.7L Power Stroke, the Gator Fasteners HD220 Head Stud Kit (HSK67F) replaces weak factory bolts with high-strength HD220 alloy.

This proprietary material delivers 220,000 PSI tensile strength - surpassing 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 included 12-point chromoly nuts and Gator Juice assembly lube ensure accurate torque application and optimal clamp load retention during installation.

Vehicle Compatibility: Fits 2011-2025 Ford F-250, F-350, F-450, and F-550 Super Duty trucks with 6.7L Power Stroke engines. Follow included torque sequences for optimal results.
