This is an optional SSD 2-Speed Transmission Conversion Kit for a SCX10 II equipped with the updated transfer case transmission; this conversion is not compatible with the older AX10 transmission that comes included with the RTR SCX10 II.

This conversion kit is a direct swap with the SCX10 II transfer case transmission and SCX10 II chassis. You will need to provide an additional shifting servo, and you will need an extra channel on your transmitter, but this conversion kit will allow you to take advantage of the 2-speed capabilities of the SCX10 II kit. 

Note: This is a conversion kit, not a complete transmission. Requires shift servo and extra channel on radio.

SSD RC SCX10 II 2-Speed Transmission Conversion Kit
The package went about 2 weeks, everything came in the best possible way. The kit is good, it’s a pity that there is no instruction, so this is not the maximum rating. I had to search the Internet for a long time to understand how to assemble a checkpoint. Otherwise, there are no questions. All was enough, even some spare parts remained. The installed kit in the box works without problems and complaints. Recommend.

SSD RC SCX10 II 2-Speed Transmission Conversion Kit
This kit works great. Was able to shim everything to get rid of play in the trans, greatly reducing gear noise from stock. Shifts flawlessly. Also has the highest range on the market at 108:1. Gives my crawler the perfect balance between high and low.
