The Tamiya 9803491 Suspension Arm Bushing B is a go-to part for racers who want crisper suspension movement on a TRF421 chassis. Built to reduce play and resist wear, these bushings help maintain steady handling during track sessions.
Precision moulding ensures a snug fit with TRF421 suspension points, cutting friction and improving consistency through corners. The durable construction lowers the chance of frequent replacements so you can focus on setup and lap times.
