Front hubs, rear axles, and all 4 rotors at a minimum. If he had the 10.5" rear axle with the 7 lugs then they had to swap the entire axle housing as I don't believe the axles out of a 10.5 will fit in a 9.75 housing.

wallysheata, (or anyone else) this is exactly what I am looking to do with my truck. can you tell me if you had to do any trimming to make it fit? Second question is how much lift over stock did this set up make it total?
thanks

Well I've been lurking here for a while and thought i'd make my first post a pic of new F150. We recently sold our Audi Allroad and my F350 Powerstroke to get a more suitable daily driver/tow rig for my wife. With a new baby and me working out of town, we wanted something reliable, safe, with plenty of room and the ability to tow the buggy or Wrangler LJ on the weekends. We test drove a new Diesel Grand, 5.7 Hemi Grand, 20014 F350 Powerstroke and an F150 Ecoboost. We were all flat out floored at how well the ecoboost drove, towed and the abundance of room it had over an F350. So we ordered up a 2014 F150 Lariat 4x4 Super Crew with the 6-1/2' bed, fully loaded which arrived in late March 2014. The rig tows the buggy no problem, and actually pulls the hills stronger than our chipped 7.3 Powerstroke 
, yet is still as quiet as a luxury sedan and snappy as a sports car.
This past weekend, we installed the Autospring leveling kit for our F150. We did the 2.5" front strut spacer with the 3" blocks in the rear (nets 1-3/4" lift over the factory 1-1/4" block). For wheels we picked up a set of 20x8.5 F150 Platinum wheels and ordered up some 305/60-20 Goodyear Wrangler Silent Armors which measure out at 34.45" x 12.3" - 20. We couldn't be happier with how the thing looks, it rides great, no different than stock, and did not notice any power loss from the larger tires, this thing is still as snappy as ever.
For reference here's stock vs. leveling kit & 35's

Sorry for the late response, my buddy is part owner of the dealership so we did it one night after work. He had a low mileage 2012 XLT that he got on trade so we just swapped the unit bearings and axle shafts from that truck then i did new rotors and pads front/rear. Took about 4 hours total to do the swap. As for trimming, no trimming was required to clear the tires with that kit. I will say however my fuel mileage did take a huge hit. Empty i get around 14mpg on the highway, and 11-12mpg around town, and towing our 4,000 jeep on a 1,500lb trailer we average around 7mpg. The truck currently has 11,000 miles so i'm hoping by the time it hits 20,000 i see at least 1-2mpg increase i've read over and over again these truck take at least 20,000 to break in.

Nice looking truck.
Would you attribute the decrease in mileage to the increase in height or the increase in tire diameter? Or both?
I installed 255/80-17's on my '12 recently and the power is down slightly (downshifts more often) and the mileage is down a touch too. I was able to put these tires on with no lift so I figure my mileage is down due to both the added height (.75-1") higher and the load on the engine.
Thoughts?
