YR-X12 Front Upper A-arm Mount (Right) - Aluminum YX-09R by Yokomo  [YX-09R]

Right-side front upper arm mount

This aluminum front upper A-arm mount is made for 1/12 scale on-road competition cars and is specified for the right side only. It replaces the stock upper arm mount to provide a firmer attachment point in the front suspension without altering the original suspension geometry.

Fitment is limited to the listed YR-X12 platform variants; install using the existing mounting points and the original hardware where possible. No changes to servos or electronics are required, and the same screw positions are used as the factory part.

As a tuning item, this mount reduces flex at the upper arm joint, delivering more consistent steering feedback and a tighter feel under load, which helps when evaluating camber and roll-centre adjustments on 1/12 on-road setups.
