The Tamiya 54942 TRF420 Suspension Arm Bushing B is a practical spare made for the TRF420 chassis. This pack of two helps keep suspension pivots operating as intended between rebuilds and events.
These bushings match the TRF420 arm interfaces so that swapping worn items brings back tight, repeatable steering behaviour without complex modifications.
Constructed to withstand typical track use, the bushings aim to limit play and maintain a steady suspension feel, helping you spend less time tinkering and more time running laps.
