Overview
This Tekno RC CNC 43T differential ring gear is one half of the 13/43 ring and pinion set for Tekno RC EB48 and NB48 2.x 1/8 scale buggies. It must be used with its counterpart, the TKR9153B 13T pinion.
It is a direct replacement for the stock TKR9151 and TKR9153 gears, and no additional hardware is required. According to Tekno RC, the 13/43 set gives a final drive ratio of 12.2130 and offers less wheelspin on loose tracks and a good all-round balance, recommended for larger, faster tracks.
