Engineered Suspension Upgrade for the TRF421

The Tamiya 9803486 Suspension Arm Bushing A/C: 42384 is a purpose-built replacement for the TRF421 chassis that improves wear resistance and steadier suspension action. Machined to tight tolerances, these bushings cut friction to promote more consistent suspension travel and better on-track feel. They are a practical upgrade for racers and club drivers who want reliable handling and longer service intervals.

Main Benefits for Track Use

Compatibility: Made to fit the Tamiya TRF421 chassis precisely.
Durability: Constructed from robust materials to handle frequent running.
Functionality: Lowers friction for cleaner, more predictable suspension movement.

Will these bushings fit other Tamiya cars?

They are tailored for the TRF421 geometry; they might fit other models with very similar arm bore sizes but fit is not guaranteed.

How do I install them properly?

Press them into the arm bore gently, check alignment, and avoid overdriving. A light smear of low-friction grease helps during assembly.

What maintenance do they need?

Inspect for wear after heavy use and clean debris from around the arm pivot; reapply a small amount of compatible grease as needed.
