The Tamiya 49343 Belt Stabiliser is a compact upgrade for TRF415 owners looking to reduce belt lash and improve transmission smoothness. It helps the belt run truer under load and eases stress on adjacent parts.
By supporting the roller shaft with ball bearings, the stabiliser cuts down friction and uneven wear on the belt system. It is tailored for TRF415 mounting points and delivers predictable behaviour under sustained runs.
Clean the area before fitting and ensure bearings are correctly located on the shaft. Tighten fixings evenly and perform a running check at low speed to confirm alignment before pushing to race pace.
