Write a ReviewThis is an upgrade kit for the AM14U4 that includes two 3 CIM EVO Shifter gearboxes and associated mounting hardware giving your robot a serious capability boost by adding the ability to shift speeds between one for flying down the field and another for precision alignment and pushing power. We have specifically selected the ratios we think are best for the 2019 game depending on which wheel diameter you wish to use. For the 6 in. wheel version we give you the 7.56:1 and 22.67:1 ratios for final drive speeds of ~16 and ~5 ft/sec
