Engineered for Ford's legendary 7.3L IDI diesel engines, the Gator Fasteners HD220 Head Stud Kit (HSK73IDI) provides unmatched clamping force for 1988-1994 trucks. Unlike competitor kits using standard 8740 chromoly, Gator's proprietary HD220 alloy undergoes specialized heat treatment to prevent head lift under extreme cylinder pressures, making it ideal for turbocharged or high-compression builds.
Each stud is precision-forged and heat-treated before thread rolling, preserving structural integrity for reliable load retention even during repeated thermal cycles. The included 12-point nuts allow precise torque application according to manufacturer specifications, while enlarged washers protect engine deck surfaces. Whether you're upgrading injectors, increasing boost, or maintaining an aging workhorse, these studs deliver the security needed for modern diesel performance – when properly installed.
Note: Exclusively designed for 7.3L IDI engines. Not compatible with Power Stroke models.
