Tamiya 54879 TRF419 Aluminum Front Direct Cups Set (2pcs) OP-1879 - Lightweight front spool upgrade  [54879]

Reduce Rotating Mass for Sharper TRF419 Response

If you tune and race the TRF419 line, the Tamiya 54879 TRF419 Aluminum Front Direct Cups Set provides a straightforward weight saving. These aluminium cups replace the standard steel pieces in the Direct Coupling (Spool) system on your 4WD racer, helping improve responsiveness without changing geometry.

Performance Gain Compared to Steel

Each aluminium front direct cup trims rotating mass by 2.8 grams versus the steel item. Lower rotating mass improves linear response from the drivetrain and lets the car change direction more readily during tight cornering in race conditions.

Robust Fit and Broad Compatibility

The package contains two aluminium direct cups plus a swing shaft cap made from a new material for better wear resistance. These parts fit the TRF419 and are also compatible with TB Evo.6 and TB Evo.7 chassis, making them useful across multiple setups.
