Premium Main Stud Kit for 6.7L Powerstroke Trucks

If you’re building serious power with your 6.7L Powerstroke, you need more than just head studs, securing your bottom end is just as important. That’s where the ARP 250-5802 Main Stud Kit steps in. Designed specifically for 2011–2023 Ford Super Duty trucks, this kit replaces your factory main bolts with ultra-strong, heat-treated studs that keep your main caps firmly in place, even under extreme cylinder pressures and torque loads. These aren’t your average fasteners. ARP is the gold standard in diesel performance hardware, and these studs are built to handle the abuse. With the right torque sequence and care, they’re even reusable for future rebuilds. Bottom line? If you're planning to push your 6.7L past factory limits, this is a smart investment in strength and reliability. The kit includes everything you need for installation, including precision-machined studs, washers, and 12-point nuts, as well as the correct Allen hardware for a straightforward upgrade.
