1-2-3-4 Clutch Billet Piston

PISTON 1-2-3-4 CLUTCH (6L80/90) BILLET

Fits '06–'07 units that use OE part number 24224146 and '07-later units that use OE part number 24238700.

GM 6L80 and 6L90 1-2-3-4 pistons commonly crack due to cantilevered stress on the cast material. The OE part has been through several revisions in an attempt to correct this, but all OE versions are still chronically known to crack. This Sonnax heavy duty 1-2-3-4 piston is made from stronger, billet aluminum and has superior design refinements that add additional strength to prevent breakage and deliver maximum performance throughout the life of the transmission.

  • Universal design replaces early and late OE versions
  • 6061 Billet aluminum with design refinements for additional strength
