If you're diving into a rebuild or just need to get those piston rings seated right, the 901-8000 ARP 80.0mm Ring Compressor is a solid tool to have in your corner. This isn't just any old ring compressor; it’s made from durable aluminum, so you know it’s built to last. The black anodized finish not only looks sharp but also helps resist wear and tear, making it ideal for those of us who spend weekends in the garage.
Now, I won’t sugarcoat it—this isn’t an adjustable model, but honestly, that’s not a dealbreaker. If you’re working with 80.0mm pistons, this compressor fits like a glove. It’s designed to hold those rings securely, ensuring they slide into the cylinder smoothly without any nasty surprises. I've used this thing on my own projects, and trust me, it makes the whole process a lot less stressful. You can focus on getting everything else right without worrying about the rings popping out of place.
Remember, it’s sold individually, so if you’ve got a few engines lined up, you might want to grab a couple. It’s one of those tools that you’ll find yourself reaching for time and again, making it a worthwhile addition to your toolkit.

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.
