Tamiya 84045 TRF801XT Clutch Spring Tuning Kit  [84045]

Fine-Tune Clutch Engagement for TRF801XT

The Tamiya 84045 TRF801XT Clutch Spring Set gives RC racers precise control over how power is applied to the wheels. Supplied in soft, medium and hard rates, the springs let you adjust engagement to suit loose, mixed or high-traction track conditions.

Matched Spring Rates for Track Surface

Each spring rate alters the truggy's launch and mid-throttle behaviour, allowing you to choose gentler engagement for slippery corners or firmer transfer for grippy layouts. These changes let you refine acceleration without touching other drivetrain parts.

Race-Day Control and Consistency

Swapping springs helps manage wheelspin and improve predictability off the line, so you can shape lap times through setup rather than driving harder. Use the set to experiment until your TRF801XT responds consistently across laps.
