ARRMA 1/5 Kraton/Outcast 8S Shock Cap by GPM MAKXDP/CAP  [MAKXDP/CAP]

Top cap function and fitment

This aluminium shock cap is an RC-scale replacement part machined from 7075 alloy and intended for use on designated 1/5 ARRMA models and compatible GPM or original shock absorbers. It keeps the original exhaust hole to allow controlled oil and air bleed during assembly, and is designed to mate with an oil pressure cap for improved sealing of the damper assembly.

The cap is described as a direct replacement for part number ARA330568 and is supplied in a set of 4 pcs for a four-shock installation. Fitment assumes standard ARRMA top-cap geometry and common mounting interfaces used on the listed 1/5 Kraton and Outcast variants; verify existing damper tops for matching thread and seat before installation.

For tuning and maintenance, the retained exhaust hole lets trapped air escape while filling or changing oil, helping maintain consistent damping during reassembly. Use with compatible shock oil and standard shock rebuild procedures for best results.

As a direct-fit 7075 aluminium top cap option, this part is suitable for replacing worn or damaged shock caps on compatible ARRMA 1/5 models and for hobbyists seeking a machined aluminium component in their suspension rebuilds.
