The JE Pistons chrome-silicon wire wrist pin lock, 0.945-inch diameter by 0.073-inch thickness, secures piston wrist pins in high-stress engines. Wire locks spread side loads over more of the pin boss and are considered a stronger retention method than spiro locks; they install by spreading into the pin boss and require chamfered wrist pins. Hook-style and Tru-Arc variants address rotation and reusability in other applications.
