This part is a scale replacement intended to serve as the upper a-arm pivot pins on Type-C chassis. It functions as the fixed pivot that maintains the upper arm position and reduces lateral movement that can affect handling.
Installation is aimed at hobby-level maintenance: remove the old pins, inspect arm eyelets and retainers for wear, then press the new pins in with correct orientation and retention. Confirm the arm moves freely and that there is adequate clearance to adjacent components.
From a setup perspective, replacing worn upper a-arm pins helps keep suspension geometry consistent and improves steering feel during drift practice. The part is intended strictly for model RC chassis applications.
