Tamiya 50978 TB Evo III Tuners Spur Gear Set (90T, 96T)  [50978]

TB Evo III Spur Gears for Tuners

For tuners working on a TB Evo III chassis, the Tamiya 50978 Spur Gear Set supplies two Delrin gears in 90 and 96 tooth configurations. These parts are made to match the TB Evo III drive geometry and support consistent gear engagement across sessions.

Low Friction Delrin Construction

The Delrin material gives low internal friction and good dimensional stability, suitable for regular track use. The simple black finish keeps the drivetrain looking neat while resisting everyday wear.

Fitment and Swap Guide

The Tamiya 50978 set installs without modification on the TB Evo III, making it easy to test different ratios. The swap procedure is quick for those who want to fine-tune acceleration or top speed between runs.
