Arias Pistons 81mm Bore 11.3 CR
Arias Pistons has been the leader in compact piston technology since our beginning. While piston suppliers at the time focused on larger-bore domestic V-8's, Arias had the foresight to cater to smaller-bore, higher-revving, hotter-running imports and domestics.
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.
