BIG BORE XD® JL Cylinder Assist® Steering Gear – Jeep JL/JT (2018–2022) – PSC Certified Refurbished

If you’re running a full Cylinder Assist setup and putting your JL or JT to work, this is the gear built to handle it.

These are PSC BIG BORE XD® JL Cylinder Assist® Steering Gears (SG689R) for 2018–2022 Jeep JL and JT models, offered as PSC Certified Refurbished units.

Each unit has been inspected, rebuilt where needed, and tested to meet our performance standards. They may show minor cosmetic wear from prior use or handling, but they are fully functional and built to perform the same as our standard units.

This gear is designed specifically for Cylinder Assist® applications and is built to handle the added force that comes with hydraulic assist systems. Internals are upgraded for strength and durability, delivering consistent, controlled steering when the tires are loaded up and the terrain gets technical.

It’s a direct-fit solution for JL/JT platforms running EHPS systems, integrating cleanly with your setup without needing to piece things together.

If you’re already running—or stepping into—Cylinder Assist®, this is the gear that matches it.

All refurbished unit sales are final.
