This is a necessary upgrade for your Rincon or Rubicon 700 after adding a gear reduction kit. These modules are needed to correct the shaft speed @ rpm readings going to the ecm to correct high rpm auto shifting and smooth out cruising speed shifting to factory feel.
●Includes (2) modules pre-programmed to your reduction size. When checking out add in the note what size reduction you have so we can program accordingly.
***Our 28% reduction kit includes these modules. Competitor reduction kits do NOT include anything electronic to correct the speed readings.
