Tamiya 54939 Brass Adjustable Suspension Mounts (A) - Tuning Set for TRF420/TRF419/TA07/TB-05  [54939]

Chassis balance and tuning with brass mounts

The Tamiya 54939 Brass Adjustable Separate Suspension Mounts let club racers and hobbyists refine handling by increasing lower chassis weight. Made for TRF420, TRF419, TA07 and TB-05 platforms, these brass mounts give more mass than aluminum versions to help steady the car through high speed sections.

Multiple bushing choices for setup work

This kit includes a bushing sprue with seven pairs of different bushings, creating up to 25 shaft offset options. Those combinations let you experiment with roll behaviour and toe response to suit a variety of track surfaces and driving styles.

Fitment and tuning range

Designed for use on TRF420, TRF419, TA07 and TB-05 chassis, the mounts allow settings between XA and C so you can dial in toe and tracking precisely for practice laps or race day.
