The short answer is yes you will get some lift.
The more detailed answer is it really depends. Are the Rubicon springs off of a new or low mileage Rubicon? If so you can expect to gain some lift, but only about an inch maybe an inch and a half. If the springs are off an older Rubi, or one that has high miles or a lot of heavy mods then they could be somewhat worn out and you wont get nearly as much lift from them.
Also if the Rubicon Springs are the 19/60's and your current springs are say 17/58's you wont gain much of anything. The wider the gap in your numbers translates into more of a lift.
