Tamiya 54427 RM-01 Carbon Rear Shaft Upgrade Kit - Lightweight Race Tune  [54427]

Refine RM-01 Balance with Tamiya Carbon Shaft

The Tamiya 54427 RM-01 Carbon Rear Shaft replaces the standard steel rear shaft with a precision carbon component to cut weight and sharpen throttle feel. This upgrade reduces rotating mass to deliver crisper acceleration and improved mid-corner response while remaining fully compatible with the RM-01 chassis. It is aimed at racers wanting a straightforward, performance-focused swap.

Why Carbon Works for Racing

Carbon offers a high strength-to-weight ratio that helps lower inertia in the drivetrain. Fitting the carbon rear shaft typically results in quicker drive-line response and more agile handling compared to steel parts, which benefits lap times on technical tracks.
