Overview
The Tamiya TRF420 Suspension Arm Bushing B is a precision aluminum bushing insert designed for the innovative suspension arm system on the TRF420 competition chassis. These bushings allow quick, minute adjustment of damper attachment position and leverage ratio—the angle at which the shock damper operates—providing fine-tuning capability that can significantly impact handling characteristics.
The TRF420's brand-new suspension arm design uses aluminum bushing inserts rather than fixed mounting points, enabling racers to dial in their suspension setup with precision previously unavailable. The B bushings represent one position option in the comprehensive tuning system, allowing you to optimize damper geometry for specific track conditions.
