NO SUCH THING AS "BUDGET" 6" LIFT. Tell us about the lift MAYBE we can start helping? First step REMOVE the lift. Next fix what ever was damaged by the crappy lift. Then install a proper lift.

I'm going to assume that there is a huge stack of spacers up front and blocks in the rear, stock control arm pointing almost south and steering linkage geometry that looks like some sort of abstract triangle art project. Post some pics if you could, it may help the group figure out what is going on.

"Budget" in regard to lifts that high means "no corner left uncut".

As others have said your geometry is shot. With that said I'd start by taking it to someone who knows how to do an alignment on a lifted vehicle with big tires and have them fix your toe. I promise you that, although it won't fix your invariable geometric horror story - it will go a long way in toning down the wobble.

So 3 2" spacers....yup I would take those out to start with. I bet the overall wobble is a stock tracbar though.

If you have a bad caster angle like i do, you can get death wobble on bumps

Put it back the way it was. then depending on what front end parts you had replaced, if any I would do everything.

I had the death wobble on stock ride height. New tie rods fixed it.

So if I were you I would put it back to stock, cause that is a VERY bad way to lift that much, if you were only going 2" than a spacer and shackle would be sufficient.

A number of things could cause the death wobble. tire pressure, alignment, tie rods, ball joints, play in the pitman arm, track bar, control arm bushings.

I would seriously look into a proper lift. I am no lift expert at all, infact mine is not lifted yet, but when I do, its going on a Rough Country 4.5 X series lift. there is alot more involved than slapping spacers on as others have said, even at 3" longer control arms are recommended as well as an adjustable track bar. if you left all your stuff stock, then you are going to have many many more problems than death wobble.

just my .02

Actually it is 2" where you'd benefit from arms.

Cause of my DW was worn out hubs. The bearings were shot and cause everything to wear out prematurely. But, first things first, like everyone else said, remove the budget lift.
