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

Race-ready bumper parts for the Tamiya 51644 TRF420

If you want consistent performance on faster tracks, a well designed bumper helps. The Tamiya 51644 TRF420 B-Parts are a purpose-made option to swap out worn bumper components on your TRF420 chassis.

Maintains intended roll and cornering feel

The bumper geometry avoids interfering with chassis roll, helping the TRF420 stay neutral through turns. That gives drivers a reliable baseline when testing different spring and damper settings.

2mm offset body mounts for setup flexibility

With a 2mm offset in the mounts, you can shift how the body sits, which can affect front to rear balance. Use this to fine tune handling for tarmac or mixed surfaces.

Direct fitment for easier swaps and repairs

These components are tailored for the TRF420 layout for a neat fit and smooth installation. Ideal for replacing crash parts or when experimenting with small setup changes.
