This is an aluminum front upper A-arm mount designed specifically for 1/12 scale RC on-road competition use, intended for the left side of the chassis. It fits the supported Yokomo chassis YR-X12 and YR-X1219 and serves as the mounting point where the upper A-arm connects to the suspension tower.
The part is an RC-scale replacement/upgrade component made from aluminum to maintain stiffness compared with typical plastic parts, and it is intended to affect suspension geometry and handling predictably when used in setup tuning. Keep this part dedicated to on-road 1/12 competition cars to avoid mismatched applications.
Installation notes: confirm left-side orientation before fitting, remove the stock upper mount from the suspension tower using appropriate tools, transfer any necessary bushings or hardware from the original part, then fasten the Yokomo YX-09L using the factory screw locations. Check suspension travel and steering throw after installation to ensure there is no interference.
