Since this is a remanufactured product, a temporary "core charge" is added up front until we receive your original unit back. Once received and inspected, the charge will be reversed back to you. The core charge will be added to the price below. (Required)



Replace the factory valve body on your Cummins truck with the RevMax 47RE/48RE Performance Tow/HD Valve Body. RevMax uses a Renishaw probe to dial in each valve body to the reamer prior to the valve being cut and results in RevMax Valve Bodies to be .0005" within the original centerline of the bore. RevMax Valve Bodies undergo an extensive quality inspection and are dyno tested. Trained RevMax technicians specially craft each Valve Body to ensure it delivers improved performance.
