AXIAL SCX10 III JEEP WRANGLER Aluminum Outer Portal Knuckle Case Upgrade SCX3021A by GPM  [SCX3021A]

Robust aluminium outer portal housing for RC crawlers

Designed for AXIAL SCX10 III JEEP WRANGLER platforms, this RC-scale outer portal drive housing is supplied by GPM as part number SCX3021A. The piece replaces the outer knuckle arm case on front or rear portals to help support the internal gear train.

Constructed from 6061 T6 aluminium, the housing gives a stronger mounting surface than the standard plastic case and includes stainless steel cap head screws for assembly. It is suited to hobbyists seeking a durable outer case that reduces flex and maintains consistent gear mesh during slow technical crawling.

Assembly notes: the part mounts to the existing knuckle arm arrangement using the supplied 2.5x10 stainless steel cap head screws. Standard hex drivers are sufficient for installation, and care should be taken to retain correct gear preload when rebuilding the knuckle to prevent binding.
