The Yokomo S4-412BA sway bar ball is made to fit a 2.0mm aperture and creates the connection point between stabiliser and suspension arm on YZ-4S chassis. Its accurate seating ensures reliable movement of the stabiliser link under load.
This item contains two complete assemblies, handy for replacing worn links or fitting new stabiliser geometries. Compatible with several Yokomo frames like B-YZ4SF and MOR-010, it supports consistent handling during technical sections.
