Team Associated RC18T Plastic Spur Gear Set 55T/57T/59T - RC18-031 by 3Racing  [RC18-031]

Replacement spur gears for RC18T

This three piece plastic spur gear set contains 55T, 57T and 59T options to fine tune acceleration versus top speed on Team Associated RC18T electric drivetrains. The gears are sized for straightforward ratio swaps without changing the pinion, making quick setup changes at the track simple and repeatable.

Fitting is basic: remove the gearbox access cover, slide the chosen spur onto the gearbox shaft, check the mesh with your current pinion, and secure with the original retaining hardware. Verify mesh under light load and then re-check chassis fasteners to factory torque to prevent skipping. Keep existing shims or the original washer stack to maintain correct alignment.

Use this set as spare parts for routine setup adjustments or field repairs. After heavy use inspect tooth profiles for rounding or chips and replace damaged gears. These plastic spur gears are intended for scale electric RC use and not for non-RC applications.
