death wobble. what is it?

just put a 3.5 lift on.(2 bb and 1.5 spring helpers) i know this sucks but thats what i did. had it up to 65 mph no noticeable shaking or anything. i was particularly looking for a shake or something. i have seen death wobble mentioned here regularly but dont know for sure what it is, what causes it or how to fix it. the only thing i noticed is the jeep seems top heavy. thinking of wheel spacers. they are cheap. any body have any experience with them?

Death wobble is shaking at higher speeds cause of worn out components on the suspension. Usually things like a bushing or a rounded out mount

Why wheel spacers?

correct the wider the wheel base the lower the center of gravity...most go with rims with a different backspacing and wider tires

kinda looks like this

Thicker sway bars will help with the top heavy feeling

My death wobble is a quick notes version. Every case is different.

Not gonna help that much. If you want less roll looking into some different sway bars. The stock ones are okay but you want something beefer. Addco is a good brand and easy to come by. You can contact Kolak, he is a dealer on the site and is trustsed and liked by many because he generally has the best price kolak@aol.com. Here is what they are to give you an idea IRON ROCK OFF ROAD: WJ Front Sway Bar (Addco). That is for the front.

IRON ROCK OFF ROAD: WJ Rear Heavy Duty Sway Bar (Addco) thats for the rear. One or the other should be enough. Someone should chime in with more WJ expierence then myself and confirm

at least you can get yours up to 65, i can't go past 50, to much play in the wheel, trying to figure out how to fix it.

That DW is ridiculous. I would feel like an idiot driving like that.

Regarding center of gravity, unless those new wheels are very heavy, there will be no change in the vertical CG with a wider stance. Vertical CG is the elevation of midpoint of the mass distribution. Horizontal center will stay the same since the wheels will contribute evenly on both sides.

A wider stance will just decrease your chances of rollover a little. It takes more force to torque the weight of the vehicle over a longer moment arm.
