Tekno RC CNC Differential Ring Gear, 47T, for Use with TKR9153C

About this part

TKR9151C Differential Ring Gear, CNC, 47t, for use with TKR9153C. Part of a two-set ring and pinion system for fine-tuning gearing on Tekno RC EB/NB48 2.x buggies. Improved tooth engagement gives smoother acceleration and lower rolling resistance, which helps corner speed. It is a direct replacement for TKR9151 and TKR9153, with no extra hardware needed. Overdrive: in very loose conditions, these gears can be used for under or over drive. Only use it in rare cases where traction is very low. 13/43 with 14/47 gives 1.484% (13/43 in front), and 12/40 with 14/47 gives 0.7116% (12/40 in front). Note: gears must be used with their counterparts. TKR9151C goes with TKR9153C. Current 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.
