Tamiya 54219 TRF201 77T Precision Spur Gear Upgrade  [54219]

TRF201 Speed Upgrade with Tamiya 54219

For RC racers tuning a TRF201, the Tamiya 54219 48 Pitch Spur Gear (77T) is a precision replacement that swaps the stock 79T for a tighter 77T setup. The revised tooth profile reduces friction and audible gear noise while helping the car accelerate more responsively on the straights and out of corners.

Performance Advantages

Dropping to a 77T spur reduces overall gear ratio slightly, which can produce snappier acceleration without sacrificing handling stability. The finished tooth design also improves engagement consistency for smoother power transfer under load.

Compatibility and Installation

This spur is made specifically for the Tamiya TRF201 chassis and installs using standard spur hardware. Fitment is straightforward for experienced builders and hobbyists alike, and minimal adjustments to mesh are usually required for optimal operation.
