If you're diving into the world of Ford 9-inch rear ends, you know how crucial it is to have the right hardware. The ARP Ford 9in Pinion Support Stud Kit is one of those pieces that can make or break your setup. I’ve used these studs on my own builds, and let me tell you, they’re solid.
First off, the fastener style is a stud, which gives you a reliable grip when you’re torquing down that pinion support. The underhead length is a comfortable 2.000 inches, so you know you’re getting enough bite without worrying about stripping. Plus, the 12-point head style means you can get a wrench on it from just about any angle, which is a lifesaver in tight spaces.
When it comes to the nuts, they’re standard 12-point too, making it easy to swap them out if you ever need to. The thread sizes are 3/8-16 and 3/8-24, which are pretty standard and work well with a lot of setups. You’ll appreciate the quality steel construction, especially when you’re pushing your ride to the limit. The black oxide finish not only looks good but also helps resist corrosion, so these studs will hold up over time.
This kit comes complete with everything you need, sold as a set, so you won’t have to hunt down any missing pieces. Whether you’re building a street machine or a dedicated racer, having reliable fasteners like these is crucial. Trust me, you don’t want to skimp on hardware when it comes to your pinion support.

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless.
Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.
What Makes ARP Bolts So Special?Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes.
ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.
ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
