This optional 2 speed transmission for the Nitro RS4 MT, MT 2 and MT 2 18SS is a good upgrade if you want high speeds when using the truck on road or on flat to mild off road surfaces. The second gear will provide a tremendous increase of the top end speed. However we do not recommend using the two speed gearbox in off road conditions as the 2 speed gearbox replaces the slipper clutch of the truck. This set includes all the parts you need to convert your truck to a 2 speed transmission.
