GF is the only kit that's marketed for the 4wd... but the 2wd kits work just fine, you just won't have a parts warranty because it's "not the intended use". I am installing a McG's 2/4 kit on my '09 4wd and contemplating cutting the springs to a 3/5, which is about as low as you can take the front before you start having CV issues.

You will be at too much of an angle on your front CV joints and you'll wear them out or just plain ol' snap them when you put the pedal down in 4wd. I've seen it before, not pretty. You can always just do the spindles and get the rear spring kit, or just stick with springs, many ways to skin this cat.
