Did you leave the upper spring pads in? Hard to tell from the pictures. The upper spring pads have to come out front and back before the spring perch is set on top of the front spring. The spring should be loose and at the shortest/lowest setting of the adjustment jack through the bottom of the front control arm, the spring should pull out with the front wheels off the ground and no tension on the sway (both front tires off the ground same time). The spring seems too loose after the spring pad is removed but Donavin ensured it is no issue and for me it hasn't been. If you already removed the spring pads, then I have no idea what is wrong. The part # on the spring is correct, 8" tall spring 1100# compression rate.

I agree with Les, the tallest setting on the front is low low low, I have increased the spring compression rate to reduce rubbing with the kit maxed out on height (front only).
