6" lift installed now truck vibrates
Ever since Dodge went from torsion bar front ends to coil overs this has been a big complaint. Problem is, it's not uniform. I know A LOT of guys who went to simple coil spacers to level and developed a vibration so bad that they were forced to remove the leveling kit. Some don't get a hint of a problem.
Same with suspension lifts, some get vibrations bad, others ride like stock WITH THE SAME BRAND KITS!
The only ones who never seem to report vibration issues are the guys with body lifts, which makes sense, since no suspension geometry is changed.
I guess you could have your tires road force balanced, look at the balance of your drive shaft as these are common causes of vibration after a lift. But I wouldn't get my hopes up, I hate to say...

It's your rear pinion angle. If your rear drive shaft is bolted to the output shaft ( Slip yoke eliminator) of your transmission, your rear axle and yoke should be pointed directly at the u-joint at the transmission.
Your drive shaft and rear pinion should be in a strait line from the front u-joint to through the rear pinion.
I have a Jeep with a lift and had to set the rear pinion angle when I do a lift or you get vibrations on the take off from a stop.
Oh your fix is adjustable control arms or cam bolts.
