This graphite bellcrank brace attaches at the steering post zone of the YZ-4S and increases local stiffness around the bellcrank assembly. It is intended as a scale RC upgrade to limit flex where the steering linkage meets the chassis, helping the steering system hold a steadier line under load.
Compatibility and fit are aimed at the B-YZ4SF chassis series and the YZ-4S layout. The part can replace the factory steering post or be fitted alongside it, reinforcing the bellcrank area to reduce play that might affect steering precision.
Tuning note: adding rigidity at the steering post changes how servo movement translates to wheel angle, clarifying feedback for the driver and potentially requiring small adjustments to steering trim and toe settings after fitting. Test and refine handling to suit track conditions.
