I'm going to buy my lift kit in the next wwek or so, I know everyone has their own opinion on brands, but who really makes the most reliable and quality. Also I'm looking a t a 4 or 6 inch most probably a 6 inch with 33's or 35's I want to go the best performance without chopping up the body. I would appreciate a little advice from those who have already treaded these waters. I WILL be going off road this is not a street machine! I will drive it around town during the week and on the weekends anything goes! I hear axle wrap is a problem.....so is blocks out of the question or not suggested at all? I have read here that a 2" spring and an ORD 4' shackle flip? How about a a srtaight 6" spring? A little direction would be appreciated. Also, I hae factory quad shocks up front, do I want to kill them in favor of another set up? Just looking for suggestions and advice, everything I have heard and gotten from here has led me in the right direction. Ya'll have the experience here so I am relying on you all. Thanks <*)))>< 81" GMC Jimmy.............stock for now! I see a 6 inch lift in the near future!
