ARP Bolts 5/16-24 x 3.500 SS Hex Water Pump Pulley with 2.250in Fan Spacer Stud Kit - 400-3211

If you’re diving into the world of diesel performance, you’ve probably heard of ARP. They've been in the game since '68, and trust me, they know a thing or two about fasteners. These aren't just any bolts and studs; they’re designed to withstand some serious punishment. Whether you're pushing your engine to the limit or just want to make sure everything stays tight, these ARP fasteners are built to handle those extreme loads without breaking a sweat.

The ARP 5/16-24 X 3.500 SS Hex Water Pump Pulley w/ 2.250in Fan Spacer Stud Kit is a solid choice if you're looking to upgrade your setup. The kit comes with everything you need for a secure fit, and it’s made from stainless steel, so you know it’s going to resist corrosion and hold up over time. Installation is straightforward, and with a socket size of 1/2 hex and 1/8 Allen, you won’t need any special tools to get the job done.

What really stands out about these fasteners is their installation pre-load. They stretch quite a bit during installation, which means they hold everything together better than your average bolt. This is crucial for maintaining the integrity of your engine under high-stress conditions. So, if you're running high horsepower or just want peace of mind, these studs are a smart investment.

Plus, if you're working on a specific setup, you'll appreciate how these components fit. They’re designed to align perfectly with your water pump pulley and fan spacer, ensuring you get that snug fit every time. No more worrying about loose parts or that annoying rattle you get with lesser quality fasteners. Just solid, reliable performance.

So, if you’re serious about your diesel engine and want to make sure it’s built to last, give these ARP fasteners a shot. You won’t regret it.

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.
