ARP Adds 18 New Piston Ring Compressors
Automotive Racing Products, Inc. (ARP) has added 18 new bore sizes to its line of tapered ring compressors, bringing the total number available to 119 (see PDF chart). These include 77 SAE sizes that range from 3.552 inches to 4.750 inches and 42 Metric models from 75mm to 95.5 mm.
ARP’s ring compressors are CNC machined from 6061-T6 billet material and feature a true radius to compliment each individual bore size. This serves to efficiently compress the piston rings as the piston assembly is pushed into the cylinder.
The compressors feature an O-ring relief, which allows it to seat squarely on blocks with or without O-rings.
Durability is enhanced through Type 3 anodizing, assuring a long service life, and the bore size is prominently engraved on ARP compressors in 3/4-inch tall numbers for easy identification. With all of these features ARP ring compressors have become a favorite of many leading engine builders the world over.
For a complete run-down of all available sizes for 2012 see New Products section of the company website, www.arp-bolts.com, or call the ARP tech line at 800-826-3045.
