Yokomo YR-10F Pivot Ball Replacement Kit YR-15 6  [YR-15]

Replacement pivot balls for YR-10F arms

The Yokomo YR-15 6 Suspension Arm Pivot Ball kit is intended as a direct replacement pack for the Yokomo YR-10F 1/10 formula chassis. The components sit at the junction where the suspension arm meets the kingpin or bulkhead, allowing simple exchange at YR-10F mounting points.

These pivot balls are frequently replaced wear parts that affect steering precision and suspension travel; renewing worn balls helps recover consistent articulation and reduces slop at the arm pivot. The set includes 8 pcs to service both left and right positions across front and rear on a formula-style YR-10F.

Fitting is a straightforward mechanical procedure requiring access to the suspension arm and kingpin region; verify retaining hardware and fasteners, use matching replacement components, and ensure free movement once reassembled. In tuning sessions, note that pivot clearance will influence toe and caster, so check associated washers and retaining cups when swapping balls.
