Piston SetAftermarket piston set (AC12010-GS00A) supplied complete with wrist pins, designed as a direct replacement for the original equipment manufacturer assembly. Manufactured to the STD dimension so the set drops into a freshly machined block during a full engine rebuild. Purchased by forklift rebuilders, fleet maintenance shops, and independent service technicians who prefer a matched set over assembling individual pistons. Replacing all pistons together at overhaul restores balanced compression across every cylinder and avoids the wear-mismatch problems that come from mixing new and used components in the same engine.Aftermarket replacement part, cross-references original part number AC12010-GS00A.Need help confirming fit?
