ARP Main Stud Kit 4-Bolt For 1996-2001 Ford Mustang SVT Cobra 4.6L DOHC

If you're building a high-performance 4.6L 4V Ford Modular engine, ARP's 4-Bolt Main Stud Kit is a must. Factory fasteners often fail under high RPM and horsepower conditions—especially in engines pushing past 500HP. ARP studs solve this by preventing main cap walk, fretting, and oil pump failures—issues we’ve seen countless times in engines still running OEM bolts. These studs are built for serious power, and we wouldn't assemble a performance build without them.

Designed for aluminum 4.6L blocks equipped with a Cobra windage tray, this kit includes four longer studs specifically for mounting the tray. Made from 8740 chrome moly steel and rated at 200,000 psi tensile strength, the studs also feature J-form rolled threads for superior strength. They include hardened washers and hex nuts for reliable, even clamping force—perfect for high-rpm abuse and racing conditions.
