You'd get some lift, but they have a different spring rate than the Rubicon that is tuned to their special bypass shocks. I could be wrong on this last part, but I swear I read somewhere that they have a softer spring rate.
I'm sure you could use them, but the Mojave springs are pretty sensitive to added weight. I added a lightweight winch (72 lbs) and the Arcus front bumper and winch plate, which are also pretty light in weight, and my Majave dropped a half inch in the front after that change.
