Tekno RC EB48.4 Differential Ring Gear. These gears are CNC machined from high quality steel, then hardened for durability. They will provide smoother, quieter and more efficient operation than the standard gears.

These can also be used in the NB48.4, and can be combined with different ring/pinion combos if you want the option to run an under/overdrive setup. 

NOTE: This ring gear should be combined with the TKR8152 pinion gear and run as a set. This gear should not be mixed with any other pinion gears.


  • True straight cut design for maximum efficiency
  • Smoother and quieter than our standard gears
  • CNC hardened steel construction
  • Package includes one 40T ring gear
