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

HPI Sprint 55mm Ball Top Damper

This GPM ADP055 ball top damper is a 55mm plastic shock intended for HPI Sprint scale touring cars, supplied as a 1pr set with a 1.5mm coil spring plus washers and mounting screws. It is an aftermarket replacement part designed for RC-scale suspension tuning and straightforward fitment where the original-style ball-top dampers are used.

The component is primarily a structural damper cap and spring assembly rather than a sealed oil shock, so its role is to provide predictable spring preload and a simple pivot interface for setups that rely on ball-end top mounts. Expect this part to be used where a plastic cap is acceptable for weight and cost, and where the 55mm length matches the original geometry.

Installation notes: remove the wheel and upper body as required by your chassis, replace the existing top cap and spring assembly with the ADP055 set, secure with the supplied screws, and check ball-end engagement for free articulation. Use basic thread-lock on metal-to-metal fasteners if your chassis service manual recommends it.

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