The Tamiya 54943 Suspension Arm Bushing A-C set is a practical tuning aid for TRF420 owners who want more control over damper placement. These aluminium bushings make it straightforward to reposition shock mounts and test different handling setups.
Compared with the standard B bushings supplied with the TRF420, the A-C pieces shift the mounting offset to give alternative balance and roll behaviour. That makes it easier to tailor the car for different track layouts.
Designed to also work on the TA07 PRO chassis, these bushings suit drivers who swap parts between cars. The blue anodised finish improves corrosion resistance while keeping the components durable under regular track use.
