This aluminium front upper A-arm mount is produced for 1/12 scale on-road competition use and fits the left side of the chassis. It is compatible with Yokomo YR-X12 and YR-X1219 and acts as the mounting junction where the upper A-arm attaches to the suspension tower.
Offered as an aftermarket aluminium replacement, the component resists deformation better than typical plastic mounts and is intended to influence suspension geometry and handling in a reliable manner during setup changes. Reserve this part for on-road 1/12 competition applications to prevent improper fitment.
Installation guidance: make sure you are installing the left-side unit, remove the original upper mount from the suspension tower with suitable tools, move any required bushings or hardware from the stock piece to the new mount, and secure the Yokomo YX-09L into the factory screw positions. Verify suspension travel and steering clearance after mounting.
