Differential Ring Gear, CNC 43T for Use with TKR9153B - Tekno RC

About this part

CNC 43t ring gear that pairs with the TKR9153B 13t pinion. Dial in the gearing on your EB/NB48 2.x buggy with two sets of ring and pinion gears. Improved tooth engagement gives you smoother acceleration and less rolling resistance, so you carry more speed out of the corners. Direct replacement for TKR9151 and TKR9153. No extra hardware needed. OVERDRIVE: Only for very loose conditions where traction is low. Use it in rare situations only. 13/43 with 14/47 = 1.484% (13/43 in front) 13/43 with 12/40 = 0.7724% (13/43 in front) 12/40 with 14/47 = 0.7116% (12/40 in front) PAIRING: TKR9151B must run with TKR9153B. TKR9151C must run with TKR9153C. GEARING: Stock 2.x: 12t pinion (TKR9153), 40t ring (TKR9151), FDR 12.3077. Included with EB/NB48 2.x. Most punch, but more rolling resistance off power. Good for small tracks with lots of 180s, or short run-ups to jumps out of corners. New: 13t pinion (TKR9153B), 43t ring (TKR9151B), FDR 12.2130. Less wheelspin on loose tracks.
