you should be fine. Many many guys are running these level kits and rarely report the wobble. Though in most cases its only in 4wd on flat surfaces.
I get a minor vib in 4wd with my bilstein leveling shocks...but it's only noticeable on flat ground...who drives on flat ground with 4wd?
Get the kit...you'll be fine
