Tekno Ring/Pinion Gears EB/NB48 2.0/2.1/2.2 TKR9151 - Ring Gear (40t) stock gearing TKR9153 - Pinion Gear (12t) stock gearing TKR9151B - Ring Gear (43t) TKR9153B - Pinion Gear (13) 40/12 Final Drive Ratio = 12.3077  This is the stock gearing that comes with the Tekno EB/NB48 2.0/2.1/2.2 kits. Creates the most punch, but has the most off throttle rolling resistance. 43/13 Final Drive Ratio = 12.2130 This gearing will have a smoother feel, and less off throttle rolling resistance. Works well on most tracks and is a great upgrade over the stock gearing. Final drive is a little less, so this works well with the 47t spur if being used on a bigger track.  Each gear is sold separately, you will need (2) Ring Gears and (2) Pinion Gears to have a complete gear set for your vehicle.
