Does lifting cause Death Wobble?

I'd like to put some 2"-2.5" coil spacers on my 2011 JKU but I have read a lot of stuff about people having problems 'Death Wobble' after lifting their Jeep.
Am I just being paranoid?

Lifting does not cause death wobble. Death wobble is caused by a side to side harmonic wobble between the chassis and the axle, caused by excessive movement in the track bar mounts, either by flogged out bushes, bolts moving due to not torqued properly, brackets flexing or cracking etc.

Lifting the vehicle will reduce the caster angle, which will increase the likelyhood of the front wheels wobbling, which is not death wobble (like a shopping trolley wheel wobble). However, this wobbling will rapidly deteriorate the front end components and will lead fairly quickly to full on death wobble if left to continue.

Keep your caster up over 4 degrees, preferrably over 4.5 and all should be good. That said, at 2 to 2.5in lift the caster will prob still be pretty good anyways.

EDIT... What daggo66 said - good link with good explanations.

SeaComms right-and the loss of + caster isn't that great on a 2.5˝ lift, but

It will make the cornering and hiwy driving a little "flighty", it can be fixed, but doesn't cause the "WOBBLE"-

One of the main causes of the Death Wobble after lift is, guys either loosen, or change track bars and then don't reinstall them in the CORRECT manner-

If you install bigger tires, that increases your toe-in and that can add to the wobble syndrome !!

It's never simple !

Good luck

JIMBO

Let me rephrase my question...
Will adding a coil spacer lift cause the suspension/steering components to wear our prematurely?
