GPM Racing Alloy 7075 Shock Cap for GPM and Original Shock Absorbers for Arrma 1/5 Kraton 8S (MAKXDP/CAP)

Top cap description and compatibility

This aluminium shock cap is CNC-machined from 7075 alloy as a replacement component for specified ARRMA 1/5 models and fits original shock assemblies as well as compatible aftermarket dampers. It keeps the original exhaust hole to allow controlled oil and air bleed during assembly, and is designed to accept an oil pressure cap for improved sealing of the damper assembly.

The cap is listed as a direct replacement for part number ARA330568 and is supplied as a set of 4 pcs for use in a standard four-shock installation. Fitment assumes the common ARRMA top-cap geometry found on the Kraton and Outcast 1/5 variants; check thread and seat compatibility before fitting.

During servicing the retained exhaust hole helps vent trapped air while filling or changing oil, supporting consistent damping after rebuilds. Use suitable shock oil and standard rebuild techniques for reliable performance.
