Take Your Highest Horsepower Build To The Next Level

When your Ram is making four digit horsepower, every component in the drivetrain has to be ready for the challenge. The Randy's Transmission Stage 4 68RFE is built specifically for 2019-2024 Ram 2500 and 3500 trucks that demand exceptional strength on the street, at the track, or while towing heavy loads. Rated to support over 1,000 horsepower, this transmission gives you the confidence to use every bit of your truck's potential without relying on factory components that were never designed for that level of performance. The in house built billet triple disc torque converter is engineered to deliver efficient power transfer while helping maintain dependable operation under extreme torque. Additionally, the extensive list of reinforced internal upgrades is designed to improve durability where it matters most, allowing the transmission to perform consistently under relentless workloads. Whether your truck spends its weekends making passes at the drag strip or its weekdays hauling equipment across the state, this transmission is built to handle both with confidence. It is the ideal choice for owners who expect uncompromising reliability from a transmission built for serious horsepower.

Every Internal Upgrade Supports Maximum Performance

The Stage 4 68RFE combines premium components that strengthen nearly every critical area of the transmission to improve durability, clutch capacity, and hydraulic control. At the center of the build is the BabyMaker 2000 valve body, featuring a billet channel plate, billet accumulators, TransGo SSV valves, and an OEM Mopar solenoid block to provide precise and dependable shifting. A Sonnax input shaft, Randy's XHD input drum, billet fourth clutch hub with an extended spline, and custom machined steel center support reinforce the drivetrain for extreme power applications. Furthermore, the upgraded 2C power pack with a billet piston, fourteen low and reverse clutches, bonded pistons, heavy duty low and reverse sprag update, and TIG welded planetary assembly provide exceptional holding strength under demanding conditions. Vacuum tested pumps, new Sonnax bearings, carefully matched bushings, OEM Mopar pressure and speed sensors, and upgraded filtration components help promote long term reliability throughout the transmission. Randy's heavy duty injection moulded aluminum deep pan increases fluid capacity, improves cooling performance, and adds case rigidity during sustained towing or high performance driving. To achieve the intended performance, the manufacturer also provides recommended tuning specifications that include line pressure settings, converter lockup strategy, low and reverse sprag holdout, and disabling the underdrive pulse test for 2019 and newer trucks.
