The RevMax Billet 68RFE V2.0 TUNELESS Valve Body (Part # 68RFE-301BTNLS) offers the ultimate upgrade for strength, fluid consistency, and long-term transmission reliability in 2019–2024 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel and 68RFE blue plug style transmission. When pushing your truck to its limits with heavy towing, high horsepower, and intense torque, standard transmission components can easily become the weak link. Built without the need for custom transmission tuning or external pressure box modules, this drop-in solution elevates line pressure up to 210 PSI directly out of the box with zero pump modifications required. By utilizing high-precision CNC machining on state-of-the-art Haas mills with Renishaw probing technology, RevMax eliminates human error and hand-reaming flaws to hold tolerances within .0005 inches. Every single unit is assembled by expert technicians in Charlotte, North Carolina, vacuum-tested, and computer-dyno verified on a Hydratest bench at real-world operating temperatures to prevent valve sticking, sideloading, and early component breakdown.

• High-Pressure Tuneless Design: Engineered to run safely up to 210 PSI of line pressure without needing transmission tuning, pressure box modules, or pump modifications.

• Precision-Machined Billet Construction: Made with a 6061 billet aluminum channel plate featuring precision cutouts, a micro-polished worm track surface flat within .0003 inches, and deep, full-depth worm tracks that eliminate converter drag, TCC apply/release issues, and common P1776/P0871 trouble codes.

• Patented Heavy-Duty Accumulator Plate: Includes a steel accumulator plate three times thicker than stock using no-drill installation technology, paired with triple-seal billet accumulator pistons that replace fragile OEM plastic units.

• Redesigned Fluid Flow & Leak Prevention: Built with a specialized tuneless separator plate, Billet Steel SSV solenoid switch valve, end plugs, upgraded fasteners, and enhanced case seals to prevent cross-leaks, warpage, and circuit pressure loss.

• Enhanced Shift Quality: Proprietary RevMax accumulator springs refine the 3-4 shift feel for noticeably smoother, more consistent gear transitions under load.

• Universal Pan Compatibility: Designed to fit seamlessly with both stock OEM oil pans and aftermarket high-capacity pans.

• American Hand-Assembled Reliability: Hand-assembled and fully computer-tested by RevMax professionals in Charlotte, NC (note: solenoid pack is not included and sold separately).

By resolving the core mechanical design flaws inherent to the factory 68RFE, this valve body delivers the hydraulic control and rugged durability your heavy-duty Ram requires to tackle tough jobs with confidence. The combination of thick billet construction, proprietary accumulator springs, and leak-free fluid routing mitigates internal wear while optimizing overall shifting dynamics under maximum load. Investing in the RevMax V2.0 Tuneless Valve Body provides your 6.7L Cummins with an elite, race-grade hydraulic foundation that preserves your transmission without requiring additional software alterations.
