I put a 2" leveling kit on the front end of my 2015 F150 SuperCrew. If I put anything in the bed or on the hitch it looks like I'm doing a wheelie with the front end higher than the back! Because of this I would like to add a rear 1" or 1.5" lift block/spacer? Has anyone done this... if so, what size should I go with and will I need to buy new U-bolts?

 

the size of the block is purely up to you. depends if you want a rake for frequent towing/hauling or leveled out. the further you get the leaf springs away from the axle the greater the torque on the leaves and higher propensity of axle wrapping. could also replace the entire spring pack or insert an add-a-leaf; they can all get the hind end up 1-1.5". wherever you buy the parts will easily be able to match you up with the correct u-bolts.
