Tamiya 51644 TRF420 Performance B-Parts Bumper Kit  [51644]

Tamiya 51644 TRF420 bumper upgrade for club and track use

If you race regularly or push your buggy hard, a dependable bumper matters. These Tamiya 51644 TRF420 B-Parts provide a direct replacement for worn bumpers on the TRF420 chassis, keeping your car race-ready.

Designed to keep roll and handling consistent

The shape and mounting of these bumper parts are tuned so they do not upset the chassis roll behavior, helping preserve predictable handling when cornering at speed. That stability is important for consistent lap times.

Offset body mounts for precise balance tweaks

The included body mounts use a 2mm offset, so you can alter the attachment point to shift the centre of gravity slightly. That small change is useful when dialing in weight distribution for different track surfaces.

Fits TRF420 systems for straightforward replacement

Made specifically for the Tamiya TRF420 chassis, these parts fit cleanly and install without fuss. Replace damaged pieces or use them when refining your setup for better on-track performance.
