Tamiya 54938 Brass Adjustable Suspension Mounts for TRF420/TRF419/TA07/TB-05 - Precision Brass Tuning Kit  [54938]

Dial In Balance with Tamiya Brass Mounts

If you want sharper handling and extra ballast for competitive setups, the Tamiya 54938 Brass Adjustable Suspension Mounts are a direct option. Made to fit TRF420, TRF419, TA07 and TB-05 chassis, these brass mounts add mass and stability versus lightweight aluminium versions, helping drivers refine mid corner grip and overall balance.

Adjustable Tuning Options

The set includes three different mount profiles so you can try multiple geometries. A bushing sprue supplies seven pairs of bushings with varying bore sizes for suspension shafts, producing up to 25 distinct shaft offset choices. That variety makes it straightforward to tailor roll centre and weight bias for different track surfaces.

Fits TRF and TA/TB Platforms

These mounts are engineered for use with Tamiya TRF420, TRF419, TA07 and TB-05 chassis. Using the mounts and bushings in different combinations lets you move settings between XD and X positions and alter toe characteristics to suit setup goals.
