Tamiya 54935 Brass Adjustable Suspension Mount for TRF420/TRF419/TA07/TB-05 - precision weight kit  [54935]

Dial in balance with the Tamiya 54935 brass mount

The Tamiya 54935 Brass Adjustable Suspension Mount is a straightforward upgrade for hobbyists wanting finer control over handling. This brass mount adds mass to the chassis to help improve traction and straight-line stability. It fits popular platforms such as the TRF420, TRF419, TA07, and TB-05.

Added mass for improved grip

Because the mount is made from brass, it increases the car's weight compared to lighter aluminium options, which can translate to better bite in corners and steadier behaviour at speed. Racers often use brass parts to alter balance without major setup changes.

Multiple bushing positions for fine tuning

The package includes a bushing sprue with seven pairs of bushings in varying hole sizes, letting you choose from 25 different shaft offset positions. That range helps dial toe and roll center adjustments to suit different track surfaces and driving styles.

Fitment and easy installation

Made to work with the TRF420, TRF419, TA07, and TB-05 chassis, this mount installs with minimal modification. It offers a practical way to add weight and tuning options while keeping your original suspension geometry intact.
