Arias Pistons makes several part numbers for this application with a variety of different bore sizes, and compression ratios options. Please use the drop-down menus above to select the correct application for your build.

ARIAS 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.

Today, ARIAS maintains an unmatched advantage in the import and domestic compact market. Over three decades of research and development have led to the ARIAS Sport Compact shelf line.
