How's the alignment after installing that lift? That's the first place I'd look...

But did you setup the alignment or have it done on a rack professionally? A lift that big won't maintain a proper alignment without some adjustment. My .02 cents.

Sounds like you need a shimmy damper, either the dealer or after market.

You're beginning to sound like a broken record

I'm not sure but it sounds like what is known as death wobble. Commonly found in lifted rigs with BIG tires. There are many possibilities:

Believe it or not---tire balance
Wheel bearings
Alignment
Shocks

That big of a lift completely changes the steering geometry and there are quite a few inherent problems with it. Steering stabilizers will help but only masks the problem. Things need to be in better than average condition for it all to work well.
