I have an 86 blazer with FRONT-4 inch bds springs and ord hd shackles, REAR-4 inch schackle flip and I am planning on putting a 1 inch zero rate block on it, and I have rancho 9000s for a 4 inch lift. My problem is that I just blew out one front shock and the rear are going to be to short and will not be able to fully extend if I put the block on. Plus I just tried a Rancho 9000x for a 6 inch on the rear and there is only about 2 or 3 inchs of shaft showing. Anyone have any answers or part numbers for the rancho 9000x? I know this a common lift for people on this site.
