If you run a TRF415 chassis and want cleaner belt behaviour, the Tamiya 49343 Belt Stabiliser helps keep the drive train stable under load. It offers steadier power transfer and helps prevent belt whip during corner exits.
The part holds the belt line and supports the roller shaft using ball bearings to cut friction. That reduced resistance helps extend the life of the belt and associated gears on your TRF415 setup.
Install on a clean chassis and make sure bearings are fully seated on the shaft. After assembly, run a static belt check and a short low-speed test to confirm there is no rubbing or misalignment before full power runs.
