Our 2 Speed conversion kit works with an SCX10-II running the new style transmission.
This will NOT work with the older AX10 style transmission that also comes with the RTR SCX10-II.
With this kit you can shift into 2nd gear for more top end.
1st gear will remain the same speed so it will not impact your crawl ratio.
1st Gear: 2:1 (36/18)
2nd Gear 1.076:1 (28/26)
You will need to provide an additional shift servo and must have an open channel on your radio.
