Yokomo YX-09R Front Upper A-arm Mount (Right Side) - Aluminum 1/12 On-Road Front Suspension Part  [YX-09R]

Front upper arm mount, right side

This is an aluminum front upper A-arm mount for 1/12 scale on-road competition cars, intended for the right side only. The part replaces the stock upper arm mount to provide a firmer mounting point in the front suspension assembly without changing the original suspension geometry.

Compatibility is limited to the listed YR-X12 platform variants, use the provided mounting points and existing hardware during installation. No additional modifications to servo or electronic components are required for fitment, install using the same screw positions as the original part.

In tuning terms this mount helps reduce flex at the upper arm connection, offering a more consistent steering response and a tighter feel under steering load, useful when testing camber and roll-centre adjustments on 1/12 on-road setups.
