Hot Racing TRX4M Steel Helical Diff Ring/Pinion, Overdrive (12/22)

About this part

Steel helical ring and pinion overdrive, 22T ring with 12T pinion, for the 1/18 TRA TRX-4M. The spiral cut gears are stronger and run smoother than factory straight cut bevel gears, with less vibration, noise and wear. This ratio is a 10% overdrive compared with the stock 24T/12T, which raises wheel speed and is commonly used in the front for better digging. It works on the front or rear.
