Product Description
Upgrade the shifting performance and durability of your Ram Cummins transmission with the REVMAX 68RFE-301A Zeroflex Billet Tow/HD Valve Body. Designed specifically for 2011–2018 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins and 68RFE transmission, this performance valve body delivers improved line pressure control, faster shift timing, and superior durability for trucks that tow or work hard.
The Zeroflex billet construction eliminates the warping and flex issues that commonly occur with factory valve bodies under heavy load or increased line pressure. Built from a thick billet aluminum design and precision CNC machined, this valve body allows your transmission to operate more efficiently while maintaining crisp, predictable shifts even during demanding towing conditions.
Each valve body is dyno tested, vacuum leak tested, and hand assembled in the USA to ensure optimal performance and reliability before leaving the RevMax facility. The proprietary hydraulic circuits and billet upgrades address common 68RFE problems such as inconsistent torque converter clutch operation, harsh shifting, and valve body wear.

Frequently Asked Questions
What does the Zeroflex design mean?The Zeroflex billet construction eliminates the flex and warping that can occur with factory valve bodies under high pressure or towing loads, resulting in more consistent hydraulic control and better transmission performance.
Will this improve shift quality in my 68RFE transmission?
Yes. The RevMax valve body improves hydraulic control and reduces shift overlap, resulting in faster and more consistent shifts compared to the factory valve body.
Can this valve body handle increased line pressure?
Yes. The billet design allows the transmission to operate at line pressures up to approximately 325 PSI with proper tuning and supporting modifications.
Is tuning required when installing this valve body?
Tuning is not required for installation, but trucks running higher line pressure or performance builds often benefit from transmission tuning to fully utilize the valve body’s capabilities.
Does this valve body require a core return?
Many suppliers require a refundable core charge for this product. The charge is refunded once your original valve body is returned and inspected.
