I'm looking for your personal opinions about different lift kit makers. I'm looking for an 8 inch suspension lift, and I don't know what company to go with. It will be on my 1970 K5 that will be used mostly for mud and a little climbing. Would it be best to go with a 4 inch lift in back with a shackle flip, or 8 inch springs. I don't want to run blocks at all. I'm looking for all the opinions I can get since we all know that the manufacturers aren't going to tell me "Our stuff sucks, don't buy it." Thanks for the help.
