The JR-SCX609HD-BK front and rear gearbox cover is an aftermarket shell for Axial SCX6 Jeep models that outlines fitment, installation points, and the practical benefits of a brass exterior cover for servicing without implying performance increases beyond the component swap.
Compatibility notes refer to Axial SCX6 Jeep platforms. The piece is brass and acts as an external gearbox shell to ease access for maintenance or internal part replacement.
Use the cover as a direct exterior replacement when working on the gearbox area of compatible Axial SCX6 models; verify clearances and screw lengths before final assembly.
