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

Outer portal knuckle housing for scale use

This aluminium outer portal drive housing is for AXIAL SCX10 III JEEP WRANGLER platforms and is supplied by GPM as part number SCX3021A. It replaces the original outer case of the knuckle arms on front or rear portals to support and protect the inner gear set.

Made from 6061 T6 aluminum, the housing offers a stiffer mounting face than the factory plastic piece and comes with stainless steel cap head screws for secure fitment. The item is useful for builders wanting a robust replacement that keeps gear mesh steady during slow rock crawling and rough trail sections.

Fitment notes: the housing bolts to the existing knuckle arm layout using the supplied 2.5x10 stainless steel cap head screws. Standard hex drivers are adequate for installation, and you should verify gear preload during reassembly to prevent binding.
