Strengthen the foundation of your Ford 7.3L Power Stroke Diesel engine with the Gator Fasteners HD220 Heavy Duty Main Stud Kit (MSK73).

Engineered for high performance, towing, and racing applications, these main studs are manufactured from Gator's proprietary HD220 alloy, delivering an industry-leading 220,000 PSI tensile strength.

That's a step above ARP's 8740 chromoly main studs, which are rated at 190,000 PSI, giving you superior clamp load and resistance to main cap walk or fretting under extreme cylinder pressures.

Each stud features a black oxide finish for corrosion protection and is precision-machined for a direct fit for 1994-2003 Ford 7.3L Power Stroke engines when installing a Reinforcement Girdle.

The kit includes heavy-duty 12-point nuts, washers, and complete installation instructions for a straightforward upgrade. Whether your build is for daily driving, heavy towing, or competition, Gator Fasteners main studs provide the durability and reliability your engine demands.

Vehicle Compatibility: Fits 1994-2003 Ford F-250, F-350, F-450, and F-550 Super Duty trucks, 2000-2003 Ford Excursion, and 1994-2003 Ford E-Series vans with 7.3L Power Stroke Diesel engines.
