I installed the 2" AS spacers on my 07 F150 2wd SC Lariot last week. After installation and alignment, it still sits about 1 inch higher than rear. I wonder if the 07's naturally sit higher than earlier modals and I should have used a smaller kit. I guess the cheapest and best way to solve this problem is to just add a block to the rear.

 

I'd just add a lift block out back.

 

So I read on the AS website that installing the front end spacer may cause the rear to sag. I wish I would have known this in the beginning and had everything done at once. Would make more sence to order for 2WD trucks as one kit maybe discount the price or mention on the order form that only adding the front end spacer may cause the front to be higher than rear. So the only thing I can conclude is that the 2" spacer lifter the truck more that 2 inches.

 

Yeah I did the 2-1/2" leveling kit and the blocks in the rear at the same time... the rear sits about 1" taller I would say... and I think its perfect. Hopefully it wont look funny with a loaded up trailer on the hitch.
