What adjustments will I need to make so the drive shaft will not cause trouble on my 2011 f-250 reg cab 2×4 .
If I use the F250 2011 full kit. will I need to do anything with the differential geometry.

Do you have a 8-Lug F250?
Yes, it is a 2011 superduty reg cab 2×4.
Attached are the instructions for the rear kit to lower your Superduty. The kit provides for the proper alignment of the rear end after you have lowered it, so no problem there. Your essentially moving the rear axle from below the leaf to being on top of your leaf springs. This of course lowers the rear too much and the rest of the rear kit brings you back up to a 5” drop. In the old days when Ford attached the leaf springs to the frame by brackets that were riveted on it was fairly simple to remove and replace the brackets and move the leaf spring up, in 2008 Ford began welding these bracket to the frame which made much to difficult for regular guys to replace, so we redesigned the rear kit. Still it is a simple kit and allows you to set the pinion angle and can be done with hand tools at home. Also here is a link to the Factory Store for the Superduty Kit!
Let us know how you do!!
