It will be about the same. I have a stock rubicon, with stock 245 75 16 MTRs. I pulled up next to a pre- 2003 X model, had a budget boost and 31x10.5 pro comp xterrains on it. His looked a TINY bit taller side by side when ya looked hard, but just glancing at em they looked pretty close. Rubicon springs are about teh same, if not THE same height, but they are stiffer, so they dont sag as much as regular springs.
