PSC SG693R XDR Cylinder Assist Gear, Jeep JL 392 Rubicon (21-24), Special Valving

If you’re wheeling a JL 392 Rubicon, you already know it’s a beast—but the factory steering? Not quite up to the task when you throw on lockers, big tires, and hit the rocks. That’s where PSC’s XDR Cylinder Assist Steering Gear comes in.

This gear is custom-valved specifically for the 392’s EHPS system. It’s got a 16:1 ratio for smooth highway manners and a beefy 42mm sector shaft wrapped in a steel case for serious durability. The high-flow tower helps move big tires with ease, and when paired with a Cylinder Assist kit, it acts like a built-in steering stabilizer—so you get better control and less feedback from rough terrain.
