ARP 5/16-24 X 1.450 Starter Nose SS Hex Water Pump Pulley Stud Kit, 1/2 Hex, 1/8 Allen - 400-3202

If you’re diving into the world of diesel performance, you’ve probably heard of ARP. They’ve been at it since 1968, pushing the envelope on fastener technology for racing. I’ve used their stuff myself, and let me tell you, these aren’t your run-of-the-mill bolts. We're talking about head studs, main studs, and driveline fasteners that are built to withstand some serious punishment. If you’re pushing your engine to the limits, you want fasteners that can keep up—and ARP delivers.

The ARP 5/16-24 X 1.450 Starter Nose SS Hex Water Pump Pulley Stud Kit is a solid choice if you’re looking to beef up your setup. The materials they use are top-notch, designed to handle extreme loads without breaking a sweat. You’ll find that the installation pre-loads are pretty high, which means these fasteners are stretched just right during installation to ensure they hold up under pressure. It’s all about that peace of mind when you’re out on the road or the track.

One thing I appreciate is the attention to detail in the design. The socket sizes are 1/2 hex and 1/8 Allen, which makes it pretty straightforward to work with. No need for a toolbox full of random sizes—just grab your trusty ratchet and get to it.

So, if you’re serious about your diesel game, don’t skimp on the fasteners. ARP has a reputation for a reason, and after putting their products to the test, I can confidently say they’re worth every penny.

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.
