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

Ball-Top Cap Damper, 55mm for HPI Sprint

The ADP055 is a 55mm plastic ball-top damper cap intended for HPI Sprint touring cars, delivered as a 1pr kit including a 1.5mm coil spring, washers and mounting screws. It is an aftermarket replacement part for applications that use ball-end top mounts and non-sealed cap assemblies.

Designed as a spring and cap assembly rather than an oil-filled shock, this unit provides consistent preload control and a simple pivot point for setups that rely on ball-top engagement. It is useful where durability and low weight are priorities and where the 55mm length matches the original fit.

Fitting notes: remove necessary bodywork and wheels to access the top cap, swap the original assembly for the ADP055 set, secure hardware, and confirm free articulation at the ball joint. Use thread-lock on metal fasteners if recommended by your chassis guide.

Choose the ADP055 for simple, cost-effective ball-top damper cap replacement, and verify fitment on your HPI Sprint before track sessions.
