I have a 05 Lariat scab and it took a 2" to level it. Did you measure before ordering?

 

Heck, I have 2.5" and sometimes it still appears to be higher in the back.

 

mine is an 04 fx4 and it sits perfect with a 2.5" autospring kit. something must be off with your rear suspension. i think an add a leaf is in order, or a block if you dont want the added firmness

 

I have an 06' XLT Screw 2wd and I bought the 2.5 HBS level and had the same problem so I bought an 1" block from fat bob's garages website and a .5" shim from a local shop and now I have the PERFECT DAMN TRUCK! lol The block and shims were a cheap fix while maintaining an OEM quality ride. Add a leaf is too rigid for my blood.

 

 

I used the 2" setting for my Bilstein 5100's. There is still a slight offset from front to back but it looks much better than stock.
