I really like the leveling kit. And as far as I know, you can run the 35s with the kit that I have, and I think my kit was around 120.

seigell, I will try and get a pic taken of the front and the rear of the cover so you can see what it looks like. I didn't like the fit at first, but a friend of mine and I took it back off and did some modification to it so the cover would fit flush all the way around the bed of the truck. If the person who installed yours used the hardware that came with the cover and followed the instructions, I imagine you have a gap in the back by the tailgate, and possibly sticks up about a 1/2" and not flush. If so, let me know and I can tell you what I did to fix that problem.
