This only fits the 2003-2007 trucks with the 2008-2013 OEM upgraded Mopar steering installed!!!! You should have this regardless, as it is a big performance and reliability upgrade.
The provided clamp has an approximate 1.57" bore, designed to fit the OEM Mopar size steering tie rod. If you have aftermarket steering, you may need to fabricate some type of a shim if your tie rod diameter is different/smaller.
Fox 2.0 ATS (Adjustable Through Shaft) Steering Damper
Specific for the 2008-2013 Ram 2500 and Power Wagon, and 2008-2012 Ram 3500 trucks
Does not fit the solid front axle 2 wheel drive trucks.
This is the adjustable version.
Through Shaft technology prevents any internal pressure from inducing steering push/pull.
Uses metal bearing ends to be more effective and is externally adjustable.
Great for larger tires as the firmer settings are much more effective at controlling wobble.
Comes with bracket shown, needed for installation.
