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

Pivot ball set for YR-10F suspension arms

The Yokomo YR-15 6 Suspension Arm Pivot Ball is a dedicated RC-scale replacement set intended for the Yokomo YR-10F 1/10 formula chassis. The kit supplies individual pivot balls used where the suspension arm interfaces with the kingpin or bulkhead, offering straightforward swap-in compatibility with the YR-10F mounting points.

These pivot balls are small wear items that influence steering feel and suspension articulation; swapping worn balls can restore consistent motion and reduce play at the arm pivot. The set contains 8 pcs to cover both sides of a standard front/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 verify free movement after reassembly. For tuning, note that pivot wear and clearance affect toe and caster behavior, so inspect surrounding washers and retaining cups when changing pivot balls.

Compatibility

Compatible with Yokomo YR-10F chassis as listed, intended for 1/10 formula car suspension arm pivot points.

Use this set when restoring precise pivot action on YR-10F cars or keeping a spare parts supply for track maintenance and quick swaps.
