Sometimes you have to tighten the loose nut behind the throttle pedal.
But seriously, what 75F350 said, if it just recently developed, check the trans mount and u-joints. Also, I guess this question should be asked, how long has it been shaking like that? Since the lift was installed, or just recently?

What is the condition of the splines in the slip yoke / joint?
It is possible that you have some dry splines, and when the axle tries to move under acceleration, it is finding resistance at the splies causing the acceleration vibration.

I would suspect the angle has changed with the drive shaft/pinion. If there is a carrier bearing installed along the drive shaft, a fix might be to lower the carrier bearing with a spacer. But the question is how long has this been going on and is it related to the lift.
