PSC DDS Dynamic Damping Stabilizer Steering System

The XDR Cylinder Assist® gear and DDS® stabilizer work together to settle the front end and keep the steering from reacting to every bump or rut. It smooths things out and helps the Jeep stay on line instead of constantly needing correction.

This system is built to solve the drivability problems that come with lifts and larger tires. It takes the twitchy, harsh feel out of the steering and replaces it with something more controlled and predictable.

DDS also adds steering torque to the system, making it easier to turn larger tires when the terrain gets tight or technical. On longer drives, it reduces fatigue so you’re not worn out from fighting the wheel.

Everything is designed for durability and real trail use, with protected components that can handle abuse. The kit is built to install straightforward and matched to your axle and tie rod setup so it works as a complete system.
