The SCX3021BX brass inners are produced for the front knuckle assembly used on AXIAL Capra 1.9 Unlimited crawlers. These components support the steering linkage and internal gear faces in the knuckle to help preserve smooth engagement when crawling slowly over obstacles.
Machined from brass, each part keeps a reliable fit and resists wear, while also providing useful front-end weight for balance tuning. The kit includes the specific screws required, letting you replace the stock inner pieces without sourcing additional hardware.
A practical upgrade for trail and technical crawling, these brass inners give repeatable fitment and extra front ballast for the Capra 1.9 Unlimited platform.
