I got a great deal on 4 new 30x9.5x15 hankook rt03 mt. I picked up 5 tires that were new from a friends ford and he thought they were to small for 250. My issue comes with when I bolted them up the tires rubbed on my 99. I'd like to go w a 2 inch lift and a 2.5 in the rear and the only thing I can find are the front spacers and an add a leaf. I'd rather not go that route. I read on the forum awhile back u can replace ur xj front springs with a set from a grand cherokee and get some lift out of it. If so what year motor size deould I ask fo the local parts store and does this work the same w the leaf packs. Roughly how much lift would I see on new parts goin this route thanks for the help
