This RC-scale aluminum front upper A arm is made for Yokomo Drift Package configurations and fits into the aluminum upper A-arm assembly. The D-141 left and right pieces come with a blue alumite finish to provide consistent looks for front suspension in drift setups.
The component is built to integrate with the aluminum upper A-arm assembly and should be used alongside the corresponding aluminum upper A-arm rod end adapters listed in the original parts list. As an alloy replacement for the factory arm, it alters stiffness and wear patterns of the upper link, so account for this when adjusting camber and steering geometry for drifting.
Installation follows standard RC upper A-arm replacement procedures: remove the factory arm, fit the alloy piece using the specified hardware and ball ends from the drift package kit, then check alignment and full suspension travel to prevent binding.
