The RevMax Billet Low Reverse Servo for 94-07 Dodge 5.9L Cummins is a major upgrade for 47RH, 47RE, and 48RE transmissions.
The stock servo is prone to cocking in the bore, leading to binding and improper release of the low and reverse band, which can result in performance and shifting issues. This billet servo eliminates these problems with a design that guarantees it will never stick. Enhanced with a second sealing ring, it offers superior sealing capabilities, ensuring reliable operation even under high performance or heavy duty conditions. This upgrade is essential for achieving optimal transmission performance.
