ARP Bolts ARP 86-87 Buick Head Stud Kit, 8740 Chromoly, Black Oxide Finish, Hex Style - 123-4003

Alright, let’s talk about the ARP 123-4003 Head Stud Kit for your '86 to '87 Buick. If you’re diving into some serious engine work, these studs are a must-have. They’re made from 8740 chromoly steel, which means they’re tough as nails and built to handle the heat and pressure of high-performance builds.

The hex head style makes installation a breeze. You won’t need any fancy tools to get these bad boys in place—just a standard wrench will do. Plus, they come with washers, so you can be sure everything fits snugly without any surprises down the line. No need to worry about cutting or fitting them; they’re designed to drop right in, making your life a bit easier in the garage.

And let’s be real, when you're pushing your Buick to its limits, you want to know that everything is held together securely. These head studs are black oxide finished, which not only looks sleek but also adds a layer of corrosion resistance. That’s important when you’re dealing with the kind of heat that can warp lesser materials.

So, whether you’re rebuilding your engine or just looking to upgrade, this head stud kit is a solid choice. It’s straightforward, reliable, and perfect for anyone who wants to keep their Buick running strong without any drama.

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.
