Tamiya F103RM Graphite Main Shaft 3RACING F103RM-02 Lightweight Upgrade  [F103RM-02]

Graphite Main Shaft Upgrade for Tamiya F103RM

The 3Racing Graphite Main Shaft is a simple, effective upgrade for Tamiya F103RM owners who want stronger, lighter drivetrain components. Built to suit the F103RM layout, this shaft replaces the stock part to give a noticeable step up in component quality.

Benefits of Graphite Construction

Graphite combines low mass with good rigidity, which lowers rotational inertia and helps the car accelerate and respond faster. Swapping to a graphite shaft reduces weight at the center of rotation, which many racers find improves turn-in and mid corner feel without sacrificing durability.

Fitting and Care

Fitting the 3Racing shaft requires the same basic setup as the stock part on a Tamiya F103RM. Clean mating surfaces and a quick inspection for wear during installation will help the shaft run smoothly. Routine checks and light maintenance will extend service life.
