This GPM GT056 rear suspension arm set is an RC-scale replacement part finished in aluminum 6061 T6 and engineered to reduce play at the damper pivots through Delrin collars and tighter tolerances.
The parts provide multiple shock mounting positions so you can alter roll response and ride height characteristics without changing the shock bodies. The machining profile moves away from a flat stamped look toward a three-dimensional streamline shape that keeps weight reasonable while improving fit and repeatability at the chassis mounts.
Included hardware consists of stainless steel round head screws 3x12, 2pcs, sized to secure the arms to the stock mounting points. Inspect fit with the chassis before full installation to confirm alignment and smooth travel through the suspension arc.
Use these arms as a direct rear replacement on supported TRAXXAS GT4 TEC 2.0 chassis to regain tighter damper fit and to experiment with different shock angles during setup and tuning sessions.
