HPI Sprint 55mm Plastic Ball-Top Damper ADP055 by GPM  [ADP055]

55mm Ball-Top Damper for HPI Sprint

This ADP055 ball-top damper is a 55mm plastic shock cap intended for HPI Sprint scale touring cars, supplied as a 1pr set with a 1.5mm coil spring plus washers and mounting screws. It serves as an aftermarket replacement for setups that use ball-end top mounts and original-style cap assemblies.

The component functions as a cap and spring assembly rather than a sealed oil shock, so it provides predictable spring preload and a simple pivot interface for setups using ball-top mounts. It is suited where a lightweight plastic cap is acceptable and the 55mm length matches the vehicle's stock geometry.

Installation tips: remove the wheel and upper body as needed on your chassis, swap the existing top cap and spring assembly for the ADP055 set, secure with the supplied screws, and verify ball-end engagement allows free articulation. Apply basic thread-lock on metal-to-metal fasteners when your chassis manual recommends it.

Use this ADP055 set where a cost-effective plastic ball-top damper meets your needs, checking fit and articulation on your HPI Sprint chassis before competitive use.
