Zip, which levelling kit did you get, where did you get it, and how much was it?
I am undecided as to whether I want to get a levelling kit or not. I was thinking about the mini-spring packs. My thought was that I'd have to buy U-bolts anyways, and the levelling kit included them, so I wasn't going to install the springs until I decided on whether or not to get a levelling kit.
I picked up a set of V-code springs (not yet installed) to replace my sagging T-code springs. I don't mind a bit of a rake as the truck sits level when loaded up with a couple quads. I think the V-code springs might raise the front end up enough that I won't need a levelling kit, not only due to the existing spring sag, but also because they are rated for an additional 800 pounds.
