Tamiya 51644 TRF420 B-Parts Bumper Replacement Pack  [51644]

Outfit your Tamiya 51644 TRF420 with a robust bumper set

For off piste weekends or club events, having a solid bumper helps protect the chassis. The Tamiya 51644 TRF420 B-Parts serve as a simple replacement option for worn or cracked bumpers on your TRF420.

Kept light so chassis roll stays predictable

The bumper profile is shaped to avoid disturbing roll characteristics, letting the TRF420 behave the way you expect when hitting berms or flat out on straights. Predictable response is key when pushing limits.

Body mount offset for subtle balance changes

Body mounts with a 2mm offset let you tweak mounting points, giving you the freedom to nudge the centre of balance. That small adjustment can make a noticeable difference on loose or rough surfaces.

Specifically matched to TRF420 fitment

These parts are built to match the TRF420 chassis contours for an easy swap. Whether replacing crash-damaged pieces or trying a different setup, they integrate neatly with TRF420 layouts.
