ARP Bolts ARP VW/Audi 5cyl 20V 12pt Undercut Head Stud Kit 1988 Audi 80 Chromoly Black Oxide - 204-4704

If you're diving into a project with your Audi 80 from '88, you’re going to want to pay attention to the details—especially when it comes to the head studs. This ARP VW/Audi 5-cylinder 20V 12-point undercut head stud kit is a solid choice for anyone looking to boost their engine's reliability.

  • Fastener Style: Stud – these are designed for a secure fit that you can trust.
  • Undercut Stud: Yep, they’ve got that undercut design which helps with better clamping force. This means your head gasket stays sealed, even under some serious pressure.
  • Head Style: You’re looking at a 12-point head style here. It provides a bit more grip than the standard hex, so you can torque them down without worrying about stripping the heads.
  • Fastener Material: Made from 8740 chromoly, these studs are tough as nails. They can handle the heat and stress of high-performance applications without bending or breaking.
  • Fastener Finish: They come in a black oxide finish, which not only looks good but also helps prevent corrosion. A little extra protection never hurts.
  • Washers Included: You bet! You get washers with this kit, which is a nice touch. It saves you a trip to the hardware store.
  • Cut to Fit: No cutting necessary here. These are designed to fit right out of the box.

So, if you’re planning to push your Audi’s limits, these studs are a must-have. They fit perfectly in your 1988 Audi 80, and they’ll hold up under whatever you throw at them. Trust me, when it comes to engine builds, you don’t want to skimp on quality. This kit has your back.

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.
