Upper A-Arm Pins for Type-C

This is an RC-scale replacement part intended as upper a-arm pivot pins for Type-C chassis. The component serves as the pivot point for the upper suspension arm, providing a fixed mount that limits unwanted lateral play and keeps the arm aligned under load. The description here focuses on fit and role rather than detailed material grades.

Installation is straightforward for hobby-level maintenance: remove the old pins from the upper arm mount, inspect the arm eyelets and retainers for wear, then fit the replacement pins ensuring correct orientation and secure retention. Check for free rotation of the arm and clearance with nearby components before use.

In tuning, upper a-arm pins influence suspension geometry consistency and steering feedback on an RC drift setup. Replacing worn pins can reduce slop at the pivot, helping to maintain repeatable alignment during drift maneuvers and track testing. This part is intended only for model-scale RC chassis applications.
