Question by: Terry K on Jun 1, 2025, 3:36 PM

what exactly is the GC9000 series kit used for, like is it a complete power unit setup or just parts?

Answer by: Customer Support on Jun 2, 2025, 3:38 PM

Concentric's GC9000 Series falls under their DC hydraulic power unit kit lineup. It's built around a ball-style hydraulic configuration and comes as a kit format, meaning it's intended to get a DC-powered hydraulic system up and running rather than serving as a standalone component. Concentric Rockford has a solid reputation in the mobile hydraulic space, and this series fits that pattern of compact, self-contained DC power unit assemblies.
