Ford 9in Pinion Support Stud Kit 12pt.

The ARP Ford 9in Pinion Support Stud Kit 12pt is a precision fastening solution engineered for Ford 9-inch differential pinion support applications. This five-stud set features 3/8-16 threaded studs measuring 2 inches in length, paired with 12-point nuts for secure, repeatable installation.

Manufactured from chromoly steel with a black oxide finish, these studs deliver the corrosion resistance and strength required in high-stress differential environments where reliability directly impacts drivetrain integrity. Chromoly construction elevates strength-to-weight ratio compared to standard fasteners, critical for differential assemblies that cycle through load reversals during acceleration and deceleration.

This kit serves builders and technicians restoring or upgrading Ford 9-inch differentials in performance applications—street rods, muscle cars, off-road vehicles, and drag racing platforms. Whether rebuilding an original assembly or reinforcing a differential for increased power output, this kit ensures proper clamp load distribution across the assembly.
