The Stage4R transmission kit is our intermediate-level trans upgrade kit thats built for drag racing, sled pulling, towing and daily-driving. This kit works well for a stock truck, but was engineered to handle a Duramax engine that's been equipped with multiple high-performance modifications: such as performance tuning, oversize injectors, and/or small nitrous kits.

This kit includes our valve body recalibration kit (recalibration kit does not change shift points, only increases clutch holding power), converter flow valve and upgraded high-friction C1, C2, C3 and C4 clutches.
