There are a few combos you can put in the front to go with the chevys. there are the wrangler lift Ranchos 44044, stock rears are popular, or you can hunt a junk yard to find spring packs and build a set yourself.
If you plan on doing gears and a lift I'd bet you be wheeling in no time.
Personally, I think 35's will get you anywhere you need to go. Anything bigger is asking to break stuff. That is from experience.
