ARP Bolts ARP VW/Audi 5 Cylinder 20V 12PT Head Stud Kit for 1988 Audi 80, 8740 Chromoly - 204-4207

If you’re diving into a head stud upgrade for your Audi 80, you’re in for a treat with this ARP 5 Cylinder 20V 12PT Head Stud Kit. Trust me, these aren’t just any bolts; they’re crafted from 8740 chromoly, which means they’re tough as nails and designed to handle the heat and pressure of high-performance engines.

Now, let’s talk about the details. These studs come with a sleek black oxide finish that not only looks sharp but also helps resist corrosion. You’re getting 12-point heads here, which makes them easier to work with when you’re tightening everything down. Plus, the kit includes washers, so you won’t have to hunt around for those separately—always a bonus when you’re in the middle of a build.

One thing to note: these studs are a direct fit for the 1988 Audi 80 with the 5 Cylinder engine. No cutting or modifications needed, which is great if you’re looking for a straightforward upgrade. Just bolt them in and you’re set. With these in place, you can push your engine a bit harder without worrying about head gasket failures or warping.

In short, if you want reliability and strength in your Audi 80's setup, this ARP head stud kit is a solid choice. It’s tough, fits like a glove, and gives you peace of mind for whatever driving you throw at 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.
