Yokomo YR-10F Suspension Arm Pivot Balls - YR-15 6  [YR-15]

YR-10F pivot ball set overview

The Yokomo YR-15 6 Suspension Arm Pivot Ball set is a purpose-built replacement pack for the Yokomo YR-10F 1/10 formula chassis. The kit supplies individual pivot balls that mount where the suspension arm meets the kingpin or bulkhead, giving straightforward swap-in compatibility with the YR-10F mounting points.

Pivot balls are small wear items that influence steering feel and suspension articulation; replacing worn balls can restore smooth motion and reduce play at the arm pivot. This set contains 8 pcs to cover both sides of a typical front and rear suspension layout on a formula-style YR-10F.

Installation is mechanical and requires access to the suspension arm and kingpin area; check existing retaining hardware and fasteners, replace only with matching size components, and confirm free movement after reassembly. For setup work, remember that pivot wear and clearance will affect toe and caster response, so inspect washers and retaining cups when changing pivot balls.

Compatibility

Keep this kit on hand to restore accurate pivot action on YR-10F cars or for quick trackside replacements.
