This alloy adjustable upper arm is an aftermarket replacement part produced by GPM for HPI Savage-series trucks. It is intended as an RC-scale suspension component to replace the stock plastic upper arms and to provide a firmer mounting point for steering and suspension links.
The part uses an alloy construction for the arm with an integrated steel tie rod element where the steering link attaches, improving resistance to flex compared with stock materials. The adjustable geometry allows incremental changes to camber and track behavior without modifying the chassis or shock mounting points.
Installation is typical for Savage-series upper arms: remove the wheel and disconnect the stock arm from the hub and shock tower, transfer any bearings or mounting hardware if required, fit the alloy arm and secure with the supplied screws, then adjust the tie rod length for steering alignment. This component is focused on tuning steering feel and suspension consistency for off-road RC running rather than increasing top speed or torque.
Use this alloy adjustable upper arm where increased stiffness and predictable steering geometry are required, and verify fitment against your Savage-series hub and shock tower before final installation.
