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

Overview of the right-side upper arm mount

This aluminium front upper A-arm mount is supplied for 1/12 scale on-road competition cars and is intended for the right-hand side only. It supersedes the stock upper mount to achieve a stiffer mounting point while preserving original suspension geometry.

Compatibility is restricted to the listed YR-X12 family models; fit using the existing mounting holes and original hardware where possible. No additional servo or electronic modifications are required for correct assembly.

When setting up the car, this mount helps cut upper-arm flex, resulting in more repeatable steering inputs and a tighter front-end feel, which is helpful when refining camber and roll-centre settings.
