I have a 2009 F150 platinum 4x4, I installed the readylift 2" leveling kit and now the front sits about 3/4" higher than the back when measuring to center of wheel wells. What is the best route to take to level it out?

 

The best is more a personal preference than anything. You can replace the rear block, (factory is 1.25"), you can add a leaf to the rear springs (stiffer ride), you can add rear air bags, or you can change those readylift spacers to something shorter, or even go with replacement leveling shocks. At the point you are sitting at, I would find a set of 2 inch rear blocks and call it a day. Finding them could be a bit of a PITA. Back when I was looking for some, I couldn't find any true 2 inch specific, so I manufactured my own. (Pics in album). I would hope by now someone has started to manufacture them.
