ARP Bolts 5/16-24 x 1.500 SS Hex Water Pump Pulley with .250in Fan Spacer Stud Kit - 400-3203

Hey there! If you’re diving into the nitty-gritty of your diesel setup, you’ve probably heard of ARP. They’ve been in the game since '68, and trust me, they know their stuff when it comes to fasteners. These aren’t just any bolts and studs; they’re engineered to handle some serious pressure. Think about it—when you’re pushing your rig to the limits, you want components that won’t let you down.

Take the ARP 5/16-24 X 1.500 SS Hex Water Pump Pulley with .250in Fan Spacer Stud Kit, for instance. This kit is a game changer for anyone looking to beef up their water pump setup. The stainless steel construction means it’s not just tough; it’s also resistant to corrosion. No one wants to deal with rust eating away at their hard work, right?

Now, let’s talk specifics. The socket sizes you’ll need are a 1/2 hex and a 1/8 Allen, so make sure you’ve got those tools handy before you dive into the install. The installation pre-loads on these fasteners are no joke—they’re designed to be stretched quite a bit, which means they’re going to hold tight under some serious load. That’s crucial for keeping everything running smoothly when you’re out on the road (or off it).

And if you’re wondering about fitment, this kit is perfect for those who need to clear some space for their fan setup without any hassle. Just a heads up, you might need to do a little trimming, but nothing too crazy. It’s all about making sure your ride performs at its best without compromising on safety or reliability.

So, if you’re serious about your build and want fasteners that can take the heat, the ARP stud kit is worth checking out. It’s straightforward, tough, and designed for those who push their vehicles to the limit.

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.
