The Tamiya 54942 TRF420 Suspension Arm Bushing B is a straightforward replacement part made specifically for the TRF420 chassis. This two-piece set helps keep suspension linkages moving freely so your car tracks predictably during club runs and practice sessions.
These bushings are formed to match the original TRF420 suspension points, so replacing worn parts restores accurate pivot action and predictable handling across a range of track surfaces.
Manufactured to resist wear, the bushings reduce excess play and help maintain consistent suspension feel, cutting down on frequent adjustments between events.
