Install the 3Racing 64 Pitch Spur Gear 85T as part of a measured gearing change to refine acceleration and top speed trade offs. Use it when dialing in final drive for specific track layouts or surface grip levels.
This spur provides predictable tooth engagement for repeatable results during setup changes. It supports incremental ratio shifts and helps maintain consistent motor load across runs when paired with appropriate pinion sizing.
Confirm centre distance and pinion interface before fitting, and set mesh with a thin feeler to avoid binding. After initial installation, perform a short break in and recheck mesh and motor temperatures as part of standard race preparation.
