Strengthen the core of your Ford 6.4L Power Stroke Diesel engine with the Gator Fasteners HD220 Heavy Duty Main Stud Kit (MSK64).

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.
