PSC | 2013-2026 Doge Ram 4500 / 5500 4WD DDS Dynamic Damping Stabilizer Steering System With Lane Assist

Heavy-duty Ram trucks spend their lives towing, hauling, and putting miles on rough roads. That's exactly why PSC developed the DDS® Dynamic Damping Stabilizer Steering System.

This complete steering system combines PSC's DDS® Dynamic Damping Stabilizer Axle Kit with a BIG BORE XD® Cylinder Assist® Steering Gear to help control steering feedback before it reaches the steering wheel. The result is a more planted, controlled steering feel with less kickback, reduced driver fatigue, and increased confidence behind the wheel.

Whether you're pulling a trailer, carrying heavy equipment, or simply want a steering system that feels more stable on the highway, the DDS® system helps your Ram maintain predictable steering control without sacrificing road feel.
