ARP Bolts ARP Harley 57-73 XLS SS Head Bolt Kit, 7/16 in. Stainless Steel, Polished Finish - 460-3602

If you're diving into a project with your Harley, the ARP Harley 57-73 XLS SS Head Bolt Kit is definitely something you'll want to have on hand. This isn't just any head bolt kit; it's built for those who really care about their ride. The bolts are made from polished stainless steel, which not only looks great but also holds up against corrosion. Trust me, you don't want to be dealing with rust when you're out on the road.

Now, let's talk about the specs. You’re looking at a 7/16 inch thread size here, which means these bolts are going to fit snugly and securely. The hex head style is perfect for those of us who like to get in there with a wrench and really torque things down. And yes, they come with washers included—no need to hunt around for those. Just grab the kit and get to work.

One thing I appreciate is that these bolts are straightforward. You won't find any undercut studs here, so you can focus on getting everything aligned just right. Plus, they’re not cut to fit, which means you can count on them being the right length for your application. This kit is designed for durability and reliability, so you can hit the road with confidence knowing you've got solid hardware holding everything together.

In short, if you're looking to beef up your Harley's head assembly, this ARP kit is a solid choice. It’s built for the long haul, just like your bike. So, get ready to ride without worrying about whether your bolts are up to the task.

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.
