On the stock truck it sounded like the damper was defective. The majority (almost all ?) of the other complaints seem to be due to using larger than stock tires, with what appears to be little attention being paid to other steering/suspension upgrades.

 

I have a Tuff country coil spacer and stock shocks and have never had a problem!

 

Death wobble was an understatement of what I had. But I was in a hurry and left the 2" coil spacer on when I put the 6" lift on. I almost died several times before I had time to pull the spacers off. If I hit one bump in the road, I was fine, but God help me if I hit 2 or more in a row. I'd have to slow down to 20-25mph before it got under control.
