Tamiya 54478 Lightweight Aluminum Roll Spring Holder for F104 Ver.II and RM-01  [54478]

Tidy Up Suspension Setup with Aluminum Holders

Specifically made for the Tamiya F104 Ver.II and RM-01 platforms, the Tamiya 54478 Aluminum Roll Spring Holder offers a tidy suspension upgrade. Replacing the standard parts gives finer control over roll spring position and supports improved damper behaviour and lower joint wear.

Advantages of an Aluminum Option

Aluminum brings improved robustness while remaining light, so your car keeps its nimble feel. That mix of strength and low mass is useful whether you run club meets or want more consistent track performance.

Fitment Notes and Installation

The Tamiya 54478 fits both F104 Ver.II and RM-01 chassis types and is sold as a set of two holders. The swap-in process is simple enough for newcomers but also meets the needs of experienced builders tuning their setup.
