Does anybody use one of these. are they better than cranking up the torsion bars. Also what would be the safest amount or turns on the torsion bars before it starts screwing stuff up. Thanks

as far as i know the leveling kits on ebay are green keys and lifting block.

Yeah all the ebay kits I have seen are green keys, maybe an AAl or blocks. Cheaper to get green keys from www.gmdieseltech.com or just crank your stock keys. As to how much is ok, you can read a lot about that after searching. For a short answer, if you crank more than a few turns you will need an alignment. How do your 295s fit now?
