This RC aluminum front upper A arm is designed for use in Yokomo Drift Package setups and installs into the aluminum upper A-arm arrangement. The D-141 pair is anodized blue to deliver a uniform finish and improved surface resistance for drift use.
Intended to join the aluminum upper A-arm assembly, the arm should be used with the matching aluminum upper A-arm rod end adapters referenced in the parts list. As an alloy substitute for the standard arm, expect a change in stiffness and wear behavior that will affect suspension response and tuning choices.
Fitting is straightforward: swap the factory arm for the alloy D-141, reuse the specified hardware and ball ends from the drift package kit, then verify alignment and unobstructed suspension travel before driving.
