Tamiya 42278 TRF Large Diameter Damper Spring Set for RC Cars - Precision Spring Kit  [42278]

Tune chassis balance with Tamiya large diameter springs

For precise suspension setup on touring cars, the Tamiya 42278 TRF Damper Large Diameter Spring Set gives hobbyists sensible options. Made for TRF dampers, the kit helps refine roll and pitch for cleaner lap times.

Selectable soft, medium and hard springs

The pack supplies three distinct spring rates to tailor ride firmness to surface grip and driving approach. Springs feature a larger inside diameter than standard Tamiya components, specifically 14mm, which enhances stability under cornering forces.

Fast ID with colour-coded tubing

Included colour-coded tubing makes it straightforward to sort and swap springs between sessions. This speeds setup changes and avoids mix-ups when you are testing different rates.

Compatibility and pairing advice

These springs are optimised for TRF-style dampers and are recommended to be used with Tamiya Item 42192 TRF Damper Large Diameter Retainer (4pcs.) to ensure a correct seating and fit.
