AXIAL Capra 1.9 Unlimited Brass Inner Front Knuckle Arms by GPM SCX3021BX  [SCX3021BX]

Front knuckle inner brass parts

The GPM SCX3021BX brass inner parts are designed for the front knuckle assembly of AXIAL Capra 1.9 Unlimited scale crawlers. These RC-scale components support and stabilise the steering linkage and the inner gear interfaces in the front knuckles to help maintain smooth gear engagement during low-speed crawling and technical manoeuvres.

Each kit is machined from brass for consistent fit and durability, and the parts can also serve as external ballast to shift front-end weight where needed. The hardware set provided includes the specific screws required for mounting so you can replace the stock inner pieces without sourcing additional fasteners.

For builders tuning weight distribution or replacing worn knuckle internals on a Capra 1.9 Unlimited, these brass inner parts offer a straightforward, durable option that also adds useful front ballast for crawler setups.
