GPM Racing Brass Inner Part of Front Knuckle Arms-12pcs Set for Axial SCX10 III Jeep Wrangler Rubicon (SCX3021BX)

Precision brass inner knuckles

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.
