Vehicle | Model Year

This full hydraulic power steering pump kit is built for Jeep Wrangler YJ applications where mechanical steering is no longer part of the equation. It supplies consistent flow and pressure for full hydraulic steering systems that see real off‑road load.

Both kits include PSC CBR‑style pumps, a remote reservoir to manage fluid control, a dual‑pass cooler to handle heat, and the components needed to keep the system stable under sustained use. The difference between versions comes down to engine year and pump configuration, so you can choose the setup that matches your build without mixing parts.

This is a purpose‑built solution for off‑road YJs running full hydraulic steering and needing a pump system that works as hard as the rest of the chassis.
