AXIAL SCX10 III JEEP WRANGLER Aluminum Outer Portal Drive Housing (Outer Knuckle Case) by GPM SCX3021A  [SCX3021A]

Aluminum outer portal drive housing, RC scale

This is an RC-scale aluminum outer portal drive housing produced for AXIAL SCX10 III JEEP WRANGLER platforms, supplied by GPM as part number SCX3021A. The component replaces the outer case of the knuckle arms on either front or rear portals and is intended to stabilize the inner gear train inside the knuckle assembly.

Manufactured from 6061 T6 aluminum as specified by the source, the part aims to provide a more rigid mounting surface compared with the original plastic outer case, and includes stainless steel cap head screws for securing the housing to the knuckle. The item set is practical for model builders who want a durable replacement outer case that helps keep gear mesh consistent during slow technical crawling and scale trail use.

Installation notes: the housing mounts to the existing knuckle arm layout and uses the supplied 2.5x10 stainless steel cap head screws. No special tools beyond standard hex drivers are required, and care should be taken to maintain correct gear preload when reassembling the knuckle to avoid binding.
