If you're diving into an engine rebuild or just need to get those piston rings seated right, you might want to check out the 901-8800 ARP 88.0mm Tapered Ring Compressor. This isn’t just any compressor; it’s built from tough aluminum and has a sleek black anodized finish that not only looks good but also stands up to some serious wear and tear.
Now, I won’t sugarcoat it—this tool is straightforward and gets the job done without any frills. You won’t find any adjustable features here, but that’s part of its charm. It’s designed to fit snugly around your 88.0mm piston rings, making installation a breeze. Trust me, when you’re in the thick of an engine build, you want something reliable that won’t let you down.
Each unit is sold individually, so if you’re working on multiple pistons, just grab what you need. The tapered design really helps guide those rings into place, which means less hassle and a smoother assembly process. I’ve used this compressor on my own projects, and I can vouch for how effective it is at preventing ring distortion during installation. It’s a simple tool, but it makes a world of difference when you’re trying to get everything just right.
So, if you’re gearing up for some serious engine work, consider adding the ARP Tapered Ring Compressor to your toolkit. It’s one of those tools that you’ll appreciate having when the rubber meets the road—literally.

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.
