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.
