When your build demands the best from every component, the Stage 4 is ready to meet those expectations every time you hit the throttle.

Built Around Premium Components For Extreme Applications

The Stage 4 68RFE features an extensive list of heavy duty upgrades that work together to improve strength, hydraulic control, and long term reliability. Its BabyMaker 1000 valve body combines a billet channel plate, billet accumulators, TransGo SSV valves, and reinforced accumulator cover to provide precise transmission control under demanding conditions. A Sonnax input shaft, Randy's XHD input drum, billet fourth clutch hub, and custom machined steel center support reinforce critical internal assemblies that experience the highest loads. Furthermore, the upgraded 2C power pack with a billet piston, fourteen low and reverse clutches, bonded pistons, and heavy duty low and reverse sprag update increase clutch holding capacity while improving durability. The transmission also receives vacuum tested pumps, new Sonnax bearings, spec matched bushings, OEM Mopar pressure and speed sensors, and upgraded filtration components to promote dependable long term operation. Randy's heavy duty injection moulded aluminum deep pan increases fluid capacity to improve cooling during sustained towing or high performance driving. To achieve optimal performance, the manufacturer also supplies recommended tuning specifications for line pressure, converter lockup strategy, and low and reverse sprag operation so the transmission can be properly calibrated for its upgraded components.
