The Tamiya 51141 Dual-Speed Transmission Spring Kit is intended to improve the responsiveness of the TG10-Mk.2 transmission. By providing firmer, more predictable spring action, the kit helps maintain cleaner shifts under race conditions and during spirited driving.
These springs offer reliable preload characteristics and resist fatigue, helping to preserve shift consistency over time. They are a practical upgrade when you are fine-tuning transmission behaviour to suit specific track conditions or driving styles.
