We’ve got something new for your Jeep 4XE customers: PSC’s High-Performance Electric Power Steering Pump KIT.

This isn’t just an upgrade—it’s a serious step up. We’ve bumped pressure up to 1800 PSI (factory is only 1450 PSI), so it’s ready for big tires, lockers, and Cylinder Assist® systems.

Our exclusive Cylinder Assist® software mapping keeps steering smooth and predictable at any speed—whether you’re crawling rocks or cruising the highway. And the best part? It’s a direct bolt-in, plug-and-play install.

Key Highlights:

  • 1800 PSI for serious steering power
  • Optimized for big tires and off-road setups
  • Direct bolt-in design—no headaches
  • Designed for  PSC Cylinder Assist®
