Not enough caster. You can install dual steering stabilizers and it will most likely stop but most will tell you that is just band aiding the problem. You should also check the track bar bushing and joints for play.

strokinpower, is correct. Also check the torque of the upper track bar bolt. Whomever put the lift on may not have torqued it correctly. 405lbs is the proper torque spec.

I've also ran into a lot of DW issues on trucks running the larger BFG All Terrains like that. It seems that the sidewalls are a bit soft for these 8000lb trucks and can amplify any small issues in the front end.

Like others have said you will want to make sure that the truck has a minimum of 3 degrees of positive caster with 4-4.5 being even better. Then make sure that you don't have excessive play in the track bar bushings, track bar bracket and TRE's. Although HD or dual stabilizers will sometimes make the DW go away you will still have an underlying problem that will only get worse. Technically you should be able to drive these trucks without a stabilizer and not get DW. The main purpose of the stabilizer is to absorb the steering shock when you hit big bumps on one side or the other. This is both the transmit less feedback to the steering wheel as well as take a lot of shock stress off of components like the steering box, etc............

Let me ask this while we are all here discussing it. I had a problem with death wobble on my truck. I had all new tie rods a whole new track bar (even tried an $800 rip off guaranteed to fix your problem adjustable track bar that made the truck drive like crap) now back to a factory track bar, new drag link, all new ball joints new steering gear, different tires and a good alignment with 4 or more degrees positive caster and if I took my dual stabilizers off would have death wobble, what else is there to do?
