Our Stage 4 Transmission Rebuild Kit is an outstanding value and more than capable of getting the job done. Perfect choice for the Duramax owner who is running some higher horsepower tunes, larger turbo, larger injectors/pump and is planning on taking the truck to the track a couple times a season. This kit does not include a torque converter, a billet converter is highly recommended with this kit if running in the 550-800HP range. The DmaxStore stage 4 is ready for almost anything you can throw at it with the stock bottom end.




  • HP Rating given is with an upgraded Billet Torque Converter and Billet Internals
