The aformentioned setup is what my ThumperXJ uses currently, that is, OME springs and RE spacers on the front, and OME leafpacks with the OME JCXL AALs and RE shackles in the rear, with OME nitrochargers all the way around. Yes, it gets you four full inches of lift,(Good for 31s) yes, its soft, NO, its not tipsy, and if yer gonna go that way, youd be better off getting a full-on kit from RE, because that includes EVERYTHING in one package, and you end up spending a little less money. Ive had the OME setup for about two years now, wheeled heavily, even jumped on occasion, and no sag yet, Thump still sits as high as when I put the suspention on there. OME is EXCELLENT suspention, but as mentioned, you have to spend the extra cash for all the other lil doodads to go along with it, with no chance of adding hieght unless you bastardize it with other manufacturers parts.
