The SCX3021BX brass inner components are engineered for the front knuckle assembly of AXIAL Capra 1.9 Unlimited crawlers. These precision machined brass inserts stabilise steering linkages and inner gear contact surfaces within the knuckle to help ensure repeatable engagement during low-speed technical crawling.
Manufactured for consistent dimensional accuracy and improved wear characteristics, the brass parts also provide deliberate front-end ballast for balance tuning. The kit contains the necessary mounting screws to allow direct replacement of the stock inner pieces without additional hardware sourcing.
For hobbyists seeking a durable, precisely fitting knuckle inner and the option to shift front weight, these brass inserts offer a clean upgrade path for Capra 1.9 Unlimited builds.
