When it comes to building engines, it’s important to use precision tools that you can rely on. This is especially true when installing pistons into the cylinder bores. If you didn’t already know it, ARP offers a complete line of tapered ring compressors ranging from 3.552 to 4.750 inches, including smaller 75mm to 95.5mm diameters. Each tapered ring compressor is CNC-machined out of 6061-T6 billet tube material and is easily distinguishable by its bore size engraving.
