High performance power steering pump kit Jeep YJ 4L (1990-1994).
This high-performance power steering pump kit is built for Jeep Wrangler YJ owners who want dependable steering under real use. Both versions in this group replace tired factory components with PSC parts designed to deliver steady flow, better cooling, and consistent steering feel.
Each kit includes a remote reservoir to help control fluid aeration, a heat sink cooler to manage temperature, and properly matched hose assemblies for a clean install. The only difference between kits is the pump configuration, which changes based on model year. Everything else is designed to work together as a complete system.
This is a solid upgrade for YJs that see trail time, larger tires, or just need their steering to work the way it should again.
