Welcome to the board!
Death wobble is usually caused by several problems. Insufficient caster is a prime suspect, especially after a lift. Your alignment sheet should show what the caster is. With a lift and large tires you often need a bit more caster than stock. So the first question is, what is your caster?
Other factors are worn ball joints, loose wheel bearings, and any looseness in the suspension links and and looseness anywhere in the steering system. To find the latter, with the engine off have a buddy rock the steering wheel back and forth just to the point where the wheels begin to steer. Then examine every connection in the linkage, and slso look for the steering box of axle to be moving side to side.
The steering stabilizer is a shock absorber in the linkage. It's job is to prevent an action at the tire, like hitting a big rock, from being transmitted back to the steering wheel. It's not designed to prevent death wobble, although it will reduce it, but if the underlying cause is still there, you'll get premature tire wear and possibly premature wear to suspension and steering components.
Death wobble is a common problem that's been discussed ofter. If you do a search for "death wobble" you'll get a bunch of hits, some quite recent. Look them over for more information and other opinions.
