The Tamiya 9803491 Suspension Arm Bushing B is an essential service part for drivers who want crisper suspension action on the TRF421. Designed to limit unwanted movement, these bushings help deliver reliable contact and control across rough surfaces.
Engineered to sit precisely in TRF421 pivot points, the bushings cut friction and reduce play for more repeatable handling. Their hard-wearing composition means fewer replacements and steadier setup behaviour during long events.
