ARP Bolts 5/16-24 X 2.500 Black Hex Water Pump Pulley with 1.250in Fan Spacer Stud Kit - 100-3207

If you're diving into the deep end of performance upgrades, you’ve probably heard of ARP. They've been in the game since '68, and they know a thing or two about making fasteners that can handle some serious stress. These aren’t your run-of-the-mill bolts; we’re talking about head studs, main studs, and driveline fasteners that are built tough to take on the extreme loads that come with high-performance diesel engines.

The ARP 5/16-24 X 2.500 Black Hex Water Pump Pulley w/ 1.250in Fan Spacer Stud Kit is a solid choice for anyone looking to beef up their setup. This kit includes everything you need to secure your water pump pulley effectively, ensuring it stays put even under the most demanding conditions. The black hex finish not only looks sharp but also adds a layer of durability against corrosion.

  • Socket Size(s): 1/2 hex, 1/8 Allen

What’s really cool about this kit is how it handles installation pre-loads. Basically, when you tighten these fasteners, they stretch a bit, creating a super tight hold that keeps everything in place. That means no more worrying about your components loosening up when you’re pushing your engine to the limit.

So whether you’re racing or just want peace of mind on the street, this ARP kit has got your back. It’s all about reliability and strength, and with ARP, you’re getting fasteners that have been designed with the kind of tech that makes a difference. If you’re serious about your build, you know you can’t skimp on the details. Grab this kit and keep your ride running smooth.

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.
