Arias Forged Pistons has been the leader in compact piston technology since our beginnings. While piston suppliers at that time focused mostly on larger-bore domestic V-8’s, ARIAS had the foresight to cater to the smaller-bore, higher-revving, hotter-running imports & domestic compacts. Arias Pistons makes several part numbers for this application with a variety of different bore sizes, and compression ratios options.
