This is an axle wrap problem. Get a traction bar device our better yet replace the second longest leaf spring with one longer in the front so it reaches the front eye of the main leaf. That will stop the acceleration shudder from a stop.
Read my tale in the "acceleration shudder diagnosed by ford" thread.

I'm still investigating a change to the spring setup and avoiding the traction bars and such.

I have a 2011 Screw 6.5 box 5.0L. This shudder from a stop is making me crazy!! When unloaded it's "there", but when the bed is loaded it's much worse.This is an embarrasement for a $45K truck. Why can't Ford address this and come up with a fix?

The only real fix is traction bars or new spring setup. Both are expensive and negatively impact ride quality on a half ton so we get cheap TSB fixes hoping to reduce it to tolerable levels.
Mine is ok empty, but pulling my trailer is scary like the ujoint is about to explode under 20 mph.

i'm having the same concern with my 2012 2x4, reg cab, 78" bed, 5.0L. have had it since new, now have 2200 miles. the shudder is pronounced on take-off and at the 1-2, 2-3 shifts then seems to diminish. it's most noticeable when towing our camper, a 4400" jayco.
