Arias Forged Pistons K24A1 A2 A3 A4 A8 11.0:1 87mm STD 99mm Stroke 152

Because K20 and K24 heads all share the same 50.5cc combustion chamber volume, the compression ratio will stay the same regardless of whether you these pistons in a K24 block with a K24 head, or a K24 block with a K20 head.

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.
