I was planning to mount them on the rear only. The rear would be 15 in, front ranger rims are 14 inch. This would the raise the back exactly one inch from stock with 215/70/15 inch rear and 215/70/14 inch front. Trying to avoid buying another set of rims. One inch shouldn't play with the geometry too much.. when I bolted them on the rear, the clearance from the rim to the leaf spring was 2 1/2 inches on both rims, stock and jeep. Height certainly shouldn't be a problem. But... once they are on the rims, they are mine for better or worse.
