Need help? feel free to contact us now via livechat, phone, or email!   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. Hi-tensile forged, not cast, billet material (4032 or 2618). CNC machined working surfaces. Optimized crowns for efficient combustion. Diamond-turned ellipsoidal skirt profile. All motor/Nitrous pistons feature lightweight, high strength construction. Turbo/Nitrous pistons feature durable, heavy-duty design.
