I just did this today you will be fine with ur stock shocks but if you want, going to a little longer shock probably wouldn't hurt. I'm running my two door rear springs and four door fronts with a 3/4" level kit and still with my stock shocks

 

I wanted to just use the springs, no leveling kit. What do you think that would yield? How about the track bar?

It doesn't matter necessarily that the springs are from a 4dr Rubicon. You're really only interested in the spring part numbers.

For front springs, you'll want to install 52126319AC, commonly referred to by the last 2 digits as "19" springs.

So, if you have less than 19 springs and install 19 springs, it will help bring the front up. The higher the number, the taller the spring.

If you decide to do the rear too, you want "60" springs (68004460AA).

I did both the 19 front and 60 rear springs and gained between 1.5-2" front and rear. Bought the springs new from the dealer for under $140 total and installed in a few hours. I had 13/14 front springs and 54 rear springs originally.

 

So then , the 19's are from a JKU rubi?

 

You have to reread his first sentence. The part numbers mean more than what it came off of. A JKU Sport with an auto and max tow could have taller springs than a JKU Rubi with a manual, soft top and no tow package. So look at the part numbers on the springs and then compare to yours. The "solve-the-stock-springs" thread has tons of info and lots of "how much lift if" answers.

 

Great explanation - that's the answer I was looking for. Final question, what would you do, this method or a leveling kit?

 

You can get some decent cheep gaines out of a spring swap with some spacers. I swaped my stock unlimeted springs for springs from a rubi with tow package and installed some 1 3/4 spacers and netted 3.5 inches of lift all around. Need new shocks and rear track bar now. Rear acle pulled over about 1/2 inch but it still drives straight. And 2 inch longer shocks are needes because I can bottom out my shocks way to easy. But it looks good.

 

Rubicons do not inherently have taller/stiffer springs than any other model. Sometimes the actually have lower numbers.
