Had the ReadyLift installed today on my bone stock '07 K1500 regular cab. Had the same problem- even with the adjuster screws cranked all the way in, the front end is 1/2 to 3/4 inches lower than the rear. I even had the shop recheck all the work while I stood there and watched but still no good. Very disappointing.

 

hm... that is odd... rough country's leveling kits when cranked all the way up will set the front end about 2" higher than the rear... granted they ride like hell but if you leave the truck level it rides smooth
