Is it worth it?

I am in the process of buying stock wheels and tires off of a 2012 JKU Rubicon to install on my 2012 Sport S, He also offered the shocks and springs, I said yes on the shocks but was wanting to know if the springs would worth installing on my Wrangler it does have the tow Pk. if that makes any difference. I am not ready to do a lift at this time “only a month old the JKUR has the same mileage as mine. What is your Opinion?

the rubi springs are stiffer. it would help to level the front of your JKU, might give you a little lift all the way around. some of the guys have done that mod, i can't recall specifically.... but they gained a little.

you're not going to gain anything from the shocks alone. if the price is right, i say go for it.

Rubi springs are not necessarily stiffer. You need to check the numbers on the Rubi springs and your springs. Look at the last two digits (not letters) on all the springs. The closer to 19 in front and 60 in the rear, the stiffer they are. If you've got 14/54 and the Rubi are 18/59, then you'll end up getting quite a "lift."

I went from 17/58 in my jku to 18/59 from a jkur and that, along with a 2"/1" teraflex leveling kit gave me 3"/2". It all depends on what coils you have now and what the new ones are.

^^ This.

Since you've got the tow package, you may already have stiff springs. Can't hurt to check, though.

Make sure you check all 4 springs...the front two are sometimes different. Here's what the tag looks like...this spring's a 16, based on last two #'s:

Thanks for the input! My Sport has 14s on both front and 56 on the rear, the seller has not said what his springs are but sounds like it might be worth the swap! The price for the shocks is 50 bucks, he has not priced the springs to me yet. I do think it will be a fair from what he has priced the other parts for. Again thanks for the help!
The seller has less than 2000 miles on his JKUR

Factory 19/60's "new" can be bought for $160.
I would find out what you are getting.

Waste of time and $$$ to put similar rated springs on and get little to no lift.

You will get vastly more from shocks than you will springs. A combination of both is best if they are tuned properly, but you will gain quite a bit of wheel/axle control with the better rubicon shocks (which will be tuned to higher damping levels in front due to the heavier dana 44 - I'd hope).

Springs don't actually do much. They are "dumb". They all act the same, just differing levels of spring rate.

Shocks open up a huge realm of tuning parameters depending on what your vehicle specs are (weight, unsprung weight, travel range - low and high speed, spring rate) as well as what your needs are (hence tunable shocks for both compression and rebound)

maybe i wasn't clear... you're not going to gain any substantial lift from the shocks alone. that was the point i was trying to make. i would agree with all your other points about shocks and springs.

Man, I just looked up a full set of Bilstein's and they are only like $250!
Holy Shnitecombo. I can't wait to get my Wrangler. Shocks for my other "toys" range from about $200-$460 each (granted the latter are struts)

Just bought the Teraflex Fox with remotes. Got a great deal on them so thought i might try. Planning on posting a review in a few months once i get them installed and used.

btw great deal was still expensive ($650 shipped)

FYI - Bilstein will custom revalve their shocks. If you are in SoCal it ends up being cost effective since shipping is low (their facility is in SoCal). I've done this on my other car in order to run two different valve rates front to rear.

Teraflex 9550.

I am hopping the shocks work well/better with their coils.

I think a heavier/modded vehicle will do better with them. I have 0 mods that add weight to the jeep besides the hardtop (for now) plus a 2 door. I drive mostly city and the roads around here are terrible, I
Feel every bump. I have read the TF Shocks are slightly stiffer than stock. Will see how it go's

I wonder if they can be "or are" valved differently when bought with the lift?

I mean, I have not read one bad thing about the 5100's. People do admit they run firmer then stock but not bad.
Twice a week I run through the city and the roads are absolutely horrible. I am exhausted by the time I get home. Drive is terrible. Highway to work every day and most driving is fine. Slow/off road is great It's just the shitty roads I drive frequently that is ruff and I think a softer shock will
help.

ES9000s by Pro Comp. They suck, hard. My butt is going to thank me when I replace them.


The revalving is definitely interesting. I didn't know Bilstein was in SoCal either.

The JKUR has 18/59 springs for 80 bucks, sounds OK to me, half price with only 2000 miles. That makes it $930. for Rubi wheels, tires, shocks & springs. Sounds good to me. I checked e-bay it was more than that for wheels & tires.
