Will coils from 05 Rubi Unlimited fit 05 TJ Sport?

I just got my hands on a set of springs from a 2005 Rubicon Unlimited.

I'm looking at doing a 2" BB lift & putting 31x10.50 tires on my currently stock 2005 TJ Sport (4 ltr, 6 cyl, 6-speed manual trans).

Here's my questions:

*Will those Rubi Unlimited coils even fit properly on my TJ Sport?
*Would I gain any advantage by putting on those Rubi springs?
*Would there be any lift in my TJ with those springs on?
*Should I do the 2" BB with the Rubi coils or with my stock springs?

Thanks a million for your time!

Yes
Not really
If any, very minor.
Use the Rubi springs.

There won't be any height difference in the coils between Rubi and Sport, and they should be interchangeable. I don't believe there wouldn't be any advantage in using the Rubi springs unless something is wrong with your current ones.

Rubi springs are stiffer.

Are you sure? I was under the impression that there were some Sport configurations (e.g. dual tops) that got the same springs as the Rubicons.

I think the hard top Jeeps have the same stiffer rate as the Rubi.

Look at the labels on the springs, if present. 106AA and 130AA are the stiffest. I only found those on my 2003 Rubicon. My 05 LJ came with 105AB and 129AB springs. The lower those part numbers are, the softer the spring. Dimensions are all identical, nonetheless.

My hardtop-equipped sport had 104 rears and 128 fronts.

Thanks for all the input! I reckon that, based on above, the springs will fit my TJ Sport.

The question now, then, is whether or not I should replace my stock springs with the Rubi Unlimited ones when I do the 2" BB lift.

I'll take a look to see if I can find any number codes on the coils, as mentioned by goofus. That being said, should the stiffer of the two springs be the ones that go on my Jeep? Or the ones with the less miles, as suggested by Ironhead Jed? Or just put the Rubi ones on because they are better?
