If you're diving into a project that involves your water pump pulley, let me tell you about the 100-3206 ARP 5/16-24 X 2.250 Black Hex Water Pump Pulley with 1.000in Fan Spacer Stud Kit. This isn’t just any kit; it’s made from 8740 chromoly, which means you’re getting some serious strength and durability. These fasteners are built to withstand the heat and pressure of your engine, so you won’t have to worry about them failing when you need them most.

The black oxide finish not only looks sleek but also adds a layer of corrosion resistance. You know how it is—nobody wants to deal with rust when you’re trying to keep your engine bay looking sharp. And the hex head style? It’s super convenient for installation. You can get a good grip on these when you're tightening them down, which is a blessing when you’re working in tight spaces.

Now, let’s talk specifics. These studs are sized at 5/16-24, with an underhead length of 2.250 inches, which is perfect for most setups where you need a solid connection between your water pump and pulley. Plus, this kit comes with four studs, so you’ll have everything you need to get the job done right. Whether you're replacing old, worn-out hardware or building something fresh, this kit has you covered.

In short, if you’re looking for reliable, tough fasteners that won't let you down, this ARP stud kit is a solid choice. It’s the kind of quality that enthusiasts appreciate, and it’s built for the long haul. Grab a set and give your project the upgrade it deserves!

The Story Behind ARP Bolts

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.
