NEW! GM 6L80/6L90 1-2-3-4 Piston

GM 6L80/6L90 1-2-3-4 pistons commonly crack due to cantilevered stress on the cast material. Though the OE part has been through several revisions in attempt to correct this, all OE versions are still known to suffer from unwanted chronic cracking. Sonnax 1-2-3-4 piston 104984-01 is made from stronger, billet aluminum, making it a reliable solution for lasting results.
