This setup is built to handle the extra weight and power that come with a 392.

The XDR Cylinder Assist® gear and DDS® stabilizer keep the steering controlled and predictable, even when the front end is loaded and the tires are working hard. It takes the harsh input out of the wheel and helps the Jeep stay settled.

The system is designed to fix the real drivability issues that show up with lifts and larger tires—things like twitchy steering, constant correction, and an overall rough feel behind the wheel.

DDS adds steering torque where it matters, making it easier to turn large tires under load, especially in technical trail situations. It also reduces driver fatigue, so longer drives feel more controlled instead of wearing you out.

The pump and cooling are matched for the 392 platform, and the whole system is built to take serious use. It installs clean and works together as one complete setup.
