Hot Racing TRX4M Steel Helical Diff Ring/Pinion, Underdrive (10/24T)

About this part

Steel helical ring and pinion underdrive, 24T ring with 10T 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 20% underdrive compared with the stock 24T/12T, which slows wheel speed and is commonly used in the rear for more digging. It works on the front or rear.

You will receive

• One 24 tooth spiral cut ring gear
