Can anyone advise me about lift kits for a '94 full size bronco? I would like to know if any one kit is superior to others. I'm thinking about a 4"lift but I'm not sure what brand is best. Is it worth getting new rear springs vs. add-a leaf, vs. blocks? Is a Superrunner steering linkage of any use on a mostly highway driven vehicle? What size tires will a 4" lift allow, some say 33" others 35". Your info is greatly appreciated!
