This BD-301FR component is an RC-scale front suspension arm mount designed for the rear side of the front suspension assembly and meant for use on Yokomo BD7 and BD5 touring-car chassis. The unit is produced in blue anodised aluminium to give a firm mounting location for the suspension arm pins while remaining specific to RC applications.
Functionally, the mount secures the outer end of the front suspension arm and contributes to front suspension geometry. The left-to-right spacing between the suspension arm pins is 43.5mm; confirming that distance during fitment avoids misalignment with hub carriers and steering linkages.
Fitting advice: ensure the 43.5mm pin pitch corresponds with your chassis before installing, retain original hardware when your chassis manual suggests, and verify smooth articulation after tightening. During setup changes, this mount will influence roll centre and track width relationships and is used when adjusting front-end balance and steering feedback.
