Yes, you can definitely change the gear ratios. The internals of the 3 CIM gearbox are the same as the regular toughbox mini so you can change gear ratios using the same upgrade packages. We use the 3 CIM upgrade gearboxes with the second stage reduction changed using 24 Tooth Gear to a 40 Tooth gear. This changes the overall reduction to 5.95:1 which we find works quite well.
