ARP Bolts 5/16-24 x 3.000 SS Hex Water Pump Pulley with 1.750in Fan Spacer Stud Kit - 400-3209

If you're in the diesel game, you know how crucial it is to have the right fasteners holding everything together. ARP has been at the forefront of race fastener design since 1968, and they’ve really stepped up their game over the years. These aren’t just any fasteners; they’re built to withstand some serious stress. Think about it—when you're pushing your engine to its limits, the last thing you want is a weak link in the chain. That's where ARP's head studs, main studs, and driveline bolts come into play. They’re designed to handle extreme loads, which means you can crank up the power without worrying about failure.

One of the standout products is the ARP 5/16-24 X 3.000 SS Hex Water Pump Pulley with 1.750in Fan Spacer Stud Kit. This kit is solid; it comes with everything you need to ensure your water pump is secure and functioning at its best. The installation pre-loads are high, which means these fasteners get stretched just right during installation, ensuring a tight fit that can handle whatever you throw at it.

And let’s talk specs for a second. You’ll be working with a 1/2 hex socket and a 1/8 Allen for installation, so make sure you’ve got those tools on hand. This isn’t just about putting things together; it’s about doing it right. With ARP, you’re not just buying fasteners; you’re investing in reliability and performance. If you care about your setup as much as I do, you’ll appreciate the difference these studs make. They’re tough, they’re reliable, and they’ll keep your ride running smooth even under the harshest conditions.

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.
