Description

Engineered by Tuff Country, the 66397 Dual In-Line Steering Stabilizer is a heavy-duty solution for 4WD Dodge Ram owners running aggressive tire setups. Designed to reduce steering shimmy and sharpen handling, it’s ideal for trucks and SUVs with 35-inch tires or larger and a 4.5-inch (or greater) lift.

  • In-Line Dual Stabilizers: A compact, in-line design that pairs two stabilizers for balanced damping and steadier steering.
  • Vehicle Fitment: Compatible with 2008–2013 Dodge Ram 2500 4WD and 2008–2012 Dodge Ram 3500 4WD; requires a minimum 4.5" suspension lift and will not fit stock height.
  • Lift and Tire Compatibility: Specifically intended for 35" tires or taller, helping manage the steering forces that come with larger tires on lifted suspensions.
  • Mounting and Hardware: Includes a robust mounting bracket, secure end links, and the necessary fasteners to attach one end to the axle or frame and the other to the stock tie-rod.
  • Dust Boot Option: Dust boots are available as an add-on to help protect the shocks in harsh conditions and extend component life.
  • Durable Construction: Built to withstand demanding off-road and highway use, delivering consistent steering control under load.

The dual stabilizers work together to dampen steering impulses that can cause wandering or shimmy when you push the limits of your tire size and lift. By stabilizing the steering system, you’ll experience more predictable responses, less driver fatigue, and more confidence on rough terrain or at highway speeds. This setup is particularly advantageous for lifted Ram 2500/3500 owners who prioritize precise steering control with larger-than-stock tires.
