Tamiya 51644 TRF420 B-Parts Bumper Upgrade Set  [51644]

Protect and tune your Tamiya 51644 TRF420 with spare bumper parts

Whether you run timed heats or practice on technical layouts, a correct bumper matters. The Tamiya 51644 TRF420 B-Parts are intended as replacement bumper components that preserve the TRF420 performance characteristics.

Engineered to preserve chassis dynamics

The bumper profile has been refined to avoid upsetting roll behavior, so the TRF420 keeps predictable grip transitions and remains controllable when pushing through fast corners.

Fine-tune centre of gravity with 2mm offset mounts

The new body mounts include a 2mm offset which provides a simple way to alter attachment points and shift weight distribution slightly. Use this when adjusting handling for tighter circuits.

Specifically compatible with TRF420 chassis layout

These parts are produced to match the TRF420 chassis specifications for an accurate fit and straightforward installation. They are a practical option for repairs or incremental setup changes.
