Tech Insight

Full hydraulic steering systems eliminate the factory steering box and linkage, providing equal steering force in both directions and removing stress from traditional steering components. The 2.75 double-ended cylinder paired with a 160CC orbital valve provides balanced steering speed and torque for large-tire XJ builds.

For optimal performance and longevity, PSC recommends using PSC 715 Power Steering Fluid and installing a dedicated fluid cooler. Proper plumbing layout and heat management are critical to maintaining pump health during extended trail use.
