I am interested in swapping mine (sport) out for someones leftovers (Rubicon). Is there a spring chart out there that can guide me in the right direction? I want to a stiffer set.
Also, If anyone reads this that has a set available, let me know.

There's no chart. It varies Jeep-to-Jeep. You actually need to get under the Jeep and look at your coils.
The closer the last two numbers (not letters) are to 19 in the front and 60 in the rear, the stiffer the springs. So if you go from 14/54 to 19/60, you could end up with an inch or more of lift. If you go from 17/59 to 19/60, you might get a little lift but it'll hardly be noticeable.
Looks like I've got 14/55's. Definitely gonna go hunting for a new set. I'm holding out for a year (hopefully) on the lift/35's til next year. This will help til then.
Thanks for the help and if you hear of someone with rubi shocks/springs let me know
New ones form mopar are not that expensive. I would just get a 19/60 from them. You will find it hard to get a 19/60 off any Jeep. 18/59's are common but not really a Rubicon thing but more an Unlimited thing. the 4dr tends to have stiffer springs over a 2dr. I helped someone with a Rubicon awhile back to find out what he had and his 2dr Rubi had 15/55's. So don't assume a Rubi has better spring takeoffs. Shocks are better though.
Saying that, no matter what Chrysler has a blind monkey pick coils off the shelf during production
Great info. Thanks rics. I think I'll save myself the time and effort and give mopar a call for the 19/60's. Is it worth it to get HD shocks while I'm at it or are the stock shocks adequate? I plan on loading her down pretty good with towing/cargo.
if you get them cheap enough. Really though, go to the vendor section and look at the ZONE thread. The zone shocks are dirt cheap and though they may only last about 80% as long as better shocks they cost less then 1/2. Last I checked they were in the mid to upper $30 range per shock and a good upgrade for non rubi's. The only thing about RUbi take off is you don't know what they have gone through. Blistens are great shocks but will cost in the $80 range and Fox (better shocks) are $100 each.
I would be getting them off a brand new rubicon that had suspension upgrade the day it got delivered. Would also be getting the coils that are 19/60 where as mine are 14/56 for $150. Good deal?
Higher springs rates mean just that. It does not make them better. Many think that because these typically go on Rubicons that they must be better. This is untrue. If you plan on increasing the weight of your Jeep, using where you think bottoming out is likely, or like a stiffer ride higher rates are better.
IMHO, I would start with quality shocks, OEM or aftermarket. This is where you will see 75% of your "gains".
Wow guys... this has turned out to be a more insightful thread than I expected. From my standpoint, using my jeep as a weekend warrior towing vehicle, I need a stiffer suspension to handle the extra weight. I'm also riding pretty low on the stock suspension, so the extra 1" I'll get is a great alternative to spending the $$$ I'd have to do for an aftermarket lift (which I will get once I have the cash for tires/lift)
Ride quality is an afterthought. Its not Benz, its an off road, trail busting, rock crawling beast. Let them tires eat
:whistling: Ride quality is purely independant , as I said earlier-
My Rubi weighs inexcess of 5200 lbs and with the 19/60 combo and RS9000XL shocks--in their stiffer setting and the ride is non-bouncing/non-leaning and "SOLID"/w abrupt speed bump action-
You would get more lift but because you had less stock.
Essentially all end up the same ride height after lift install.
Ex- 2.5 lift
Somebody with 14/56 would see 3" + =73" total
Somebody with 19/60's would only see say 2" but still end up at 73" total because they were taller to start.
I have a 03 sport and was trying to figure out what springs I have but the only tag I can find is on one of the front springs... 224000 miles has worn the others off. I see the numbers 129Ab and 71765 and a long one of 52088129AB. My question is what spring do I have on this Jeep...

The Tj springs are labeled differently. I don't know if they used such a large choice of spring rates like the Jk. You guys could just have a one size fits all spring. I do think the rubicon might have a stiffer spring stock unlike the Jk where it doesn't matter.
How do you read the label on the sticker on the springs? Mine read as follows, Front:52126314AC Rear:68004256AA Then each has a split number using the whole number-Example 5212 6314AC Same amount of characters front and rear used in the split. Split number same as whole number so I know this doesn't matter. Does it help the blind monkey some how?
Not wanting to go 2.5 and 35’s. Just looking better stance and 33’s on 3.21’s.
Is it worth the effort to go from 14/56 to 17/59 and maybe add rubi Shocks? This will gain 3/4 inch?
Will rubi red shocks bolt straight in to the 14/56 set up or are they longer than then black stock shocks?
