Shaky steering
I have 2 inch leveling kit, 37-1250-20 Toyo MT. Going down the highway the steering wheel just shakes. It does not pull to one side. It just shakes.
Any opinions on what hat this might be? Dual stabilizers fix this? Did a quick search before I posted. Found nothing

I just had 295/65R20 tires installed on mine and used a different tire shop than I have in the past. I didn't put the truck on the interstate for a few days but when I did, it almost shook apart. Looked at wheels and noticed no weights. When I called the shop they said they used the sand bag method to balance them (the brand of bags was Equal I believe). I had them balance with weights. It solved the problem. He said the sand bags never broke and was never distributed inside the tires.

Could also be a loose Trac Bar or Trac Bar mount(s)... They are notorious for causing what is commonly know as "Death Wobble"... ANY play in the Trac Bar or mounts will cause Death Wobble, and it's usually at low speed when taking off from a dead stop, but can happen at other times too... Just another thought...

I have never heard of "the sand bag method" and will have to do some research on it. I would never want loose material floating around inside a tire. Sounds like a good way to jam up a schrader valve and a real mess when changing them out. But who knows, there are advancements everyday I don't keep up with.

The bump steer issue is not completely solved with these trucks, although improved. It doesn't bother me. Its a big truck with a solid front axle. Installing 37" tires is going to exacerbate the problem.

Assuming it's not the tire beads or a bad wheel balance.
Did you replace the caster bushings after the leveling kit? By raising the body the caster angle has changed on the steering knuckle. This is a topic that is near and dear to my heartburn. I chased a wobble for years which was a result of several parts being just barely within tolerances. Leveling the truck and removing the stock caster angle amplifies the bumping or jittery feeling through the steering wheel.
Some trucks struggle with this and others don't, even after leveling. Like others have said, bad track bar bushings, steering stabilizer or ball joints can all contribute to this. It's very solvable.

I had a bad wobble on my 08. Turned out to be a bum tire which I am guess was out of round. Got new tires and wobble went away.
On my 2017, I do have some wobble in the steering wheel at highway speeds that I can notice, but its not bad. Just different from previous super duties.

Also keep in mind with leveling spacers, the caster angle will be affected. My BDS 2" level kit came with caster adjustment bushings which I installed. Feels like stock to me after the level.
