TKR9153C – Diff Pinion (14t, CNC, use with TKR9151C)
Fine tune the gearing of your Tekno RC EB/NB48 2.x buggies with two new sets of ring and pinion gears. These new gears have an improved tooth engagement which offers smoother acceleration and lower rolling resistance for improved corner speed. These new ring and pinion gears are a direct replacement for TKR9151 and TKR9153 and no additional hardware is required.
Overdrive
In very loose conditions, these new gears can be used for under/over drive. Overdrive is only recommended in rare situations where traction is very low.
OD with 13/43 and 14/47 = 1.484% (13/43 goes in front)
OD with 13/43 and 12/40 = 0.7724% (13/43 goes in front)
OD with 12/40 and 14/47 = 0.7116% (12/40 goes in front)
Note
These new gears must be used with their counterparts. For instance, TKR9151B must be used with TKR9153B and TKR9151C must be used 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. Good for smaller tracks with more 180’s. Also good for tracks with short run ups to jumps out of corners.
New
13t Pinion (TKR9153B)
43t Ring (TKR9151B)
FDR: 12.2130
Reduced wheelspin on loose tracks. Less punch but smoother than 12/40 gears. Best balance. Recommended for larger/high speed tracks with more sweepers.
New
14t Pinion (TKR9153C)
47t Ring (TKR9151C)
FDR: 12.3956
Smoothest acceleration, least rolling resistance, improved corner speed for sweeping corners. Nearly a direct replacement for 12/40 gears but with improved tooth engagement.
