This graphite bellcrank brace is installed at the steering post area on YZ-4S models to raise rigidity around the bellcrank assembly. As a scale accessory it helps limit flex where steering linkages attach to the chassis, aiding a more consistent steering response under load.
Designed with the B-YZ4SF chassis series and YZ-4S layout in mind, the brace can replace the stock steering post or be added alongside it to reinforce the bellcrank area and curb unwanted movement that may affect steering feel.
Tuning impact: stiffening the steering post alters the transmission of servo inputs to wheel motion, which can make feedback crisper and change small tuning settings. After fitting, check steering trim and toe adjustments to match your handling goals.
