Keep your TRF421 race-ready with Tamiya suspension arms

The Tamiya 51742 TRF421 D Parts are suspension arms designed to sustain the handling characteristics of the TRF421 chassis. Fitting fresh arms helps avoid drift in steering feel and improves predictability on track.

Where these arms fit

Specifically matched to the TRF421 mounting points, these arms act as a direct replacement to worn pieces. Proper fit ensures correct roll centre and alignment behaviour under load.

Practical fitting advice

Tighten mounting hardware to recommended settings and confirm free movement at ball joints and hinge pins. Regular cleaning and light lubrication at pivot areas will extend their service life.
