Adjustable Brass Suspension Mounts Tamiya 54939 - A Version for TRF420, TRF419, TA07, TB-05  [54939]

Upgrade chassis stability with brass suspension mounts

The Tamiya 54939 Brass Adjustable Separate Suspension Mounts are aimed at drivers who want a heavier suspension mounting option. Suitable for TRF420, TRF419, TA07 and TB-05 chassis, the brass construction adds mass under the car to help control weight transfer and improve composure.

Broad tuning range via bushing options

Each pack contains a bushing sprue with seven pairs of bushings, giving 25 possible shaft offset positions. This selection makes it easier to tune toe and roll sensitivity to match different track grip levels and racing lines.

Compatibility notes and setup scope

These mounts fit TRF420, TRF419, TA07 and TB-05 chassis and support settings between XA and C, offering precise toe adjustment for sharper turn-in or more stable exit behaviour depending on your setup goals.
