Ford 9in S/S Pinion Support Stud Kit 6pt.

The Ford 9in S/S Pinion Support Stud Kit 6pt. by ARP is designed for automotive builders and enthusiasts seeking enhanced reliability in high-performance differentials. This kit is particularly beneficial for those running high horsepower through a Ford 9-inch rear end, where the pinion support structure experiences significant stress during various driving conditions.

Constructed from 8740 chrome moly alloy, this stud kit replaces factory bolts with high-strength alternatives that help prevent pinion walk and gear damage. The precision 6-point head design allows for effective clamping force while resisting stress concentration and fatigue cracking. The studs undergo shot-peening and stress-relieving processes to enhance their durability under cyclic loading.

This kit is ideal for high-performance applications, including street machines, drag cars, and road-course vehicles. It installs without requiring differential disassembly, making it a convenient upgrade for enthusiasts. Whether you're working with a fuel-injected 427, twin-turbo small-block, or supercharged big-block, this kit is a valuable addition to your 9-inch differential setup.
