Ford 9in S/S Pinion Support Stud Kit 12pt.

The Ford 9in S/S Pinion Support Stud Kit 12pt. is a crucial enhancement for those building Ford 9-inch differentials, particularly for high-performance drag racing and serious automotive enthusiasts. This ARP kit is designed to address a known weak point in the stock pinion support geometry, where factory fasteners may fail under extreme loads during hard acceleration or competitive use.

Constructed from proprietary aircraft-grade alloy steel, this kit undergoes ARP's signature shot-peening process to significantly enhance fatigue strength and clamp load retention. The 12-point head design ensures superior engagement, reducing the risk of rounding off during installation and removal. Each stud is precisely engineered to replace OEM pinion support fasteners, ensuring proper alignment and maintaining the integrity of the differential housing.

Ideal for Ford 9-inch differential owners looking to build high-performance applications, this kit is particularly beneficial for those upgrading to larger turbos or increasing horsepower beyond 600 hp. The corrosion-resistant finish protects against rust, making it suitable for vehicles exposed to moisture or salt. Installation requires removing the differential cover and properly torquing the new studs for optimal performance.
