Tamiya TT-01 TYPE-E Spur Gear (55/58/61T) by 3Racing TT01-28  [TT01-28]

This is an RC-scale replacement spur gear set specified for the Tamiya TT-01 TYPE-E platform offered by 3Racing as model TT01-28. It provides three tooth-count options — 55T, 58T and 61T — to let you change the overall gear ratio without altering the chassis or motor mounting.

Role and tuning: swapping among the included tooth counts is a straightforward way to fine-tune acceleration versus top speed for different track layouts or driving styles. Lower tooth counts give a higher drive ratio for quicker acceleration, while higher tooth counts favour top speed and smoother low-RPM response. Use these options to adjust performance while keeping the same pinion and motor pairing on your TT-01 TYPE-E scale model.

Installation notes: this spur gear is intended to replace the existing large gear inside the TT-01 TYPE-E gearbox assembly. When fitting, check gear mesh with the motor pinion and confirm the spur sits true on the shaft and engages the gearbox bearings without lateral play. After installation, verify smooth rotation across the drivetrain at low throttle before full-speed testing.
