Rubicon Springs and Shocks

Out of curiosity, compared to a Sport JKU, what are the benefits/bonuses to having the Rubicon Springs and Shocks?... I definitley want to beef up my JKU Sport when it comes in May, but nothing crazy. No lift for sure, but heard the Rubicon Shocks/Springs may add an inch, which I'm cool with. But besides that, are there any benefits to it?

On a related note, how good of a deal is this? Jeep Wrangler Rubicon Springs and Shocks for sale at RubiTrux

The spring rate is higher on some Rubis which will perform better when the going gets rough but it may also feel firmer when going is smooth. The shocks on Rubis are also tuned for off road performance.

Given that coils and shocks are new, it's not a bad deal. The only question is which coils but there are several models on Rubis.n There are numerous thread describing the part numbers and the general consensus is there is no reasoning behind how these different parts gets assigned to Jeeps.

Shocks are definitely better but as far as springs go it just depends on what your spring numbers are compared to the ones you are looking at. I was looking at doing the same thing but my rear springs are a 58 and the highest number is a 60 so it wan't worth the effort, I forget my front number but it was the same situation.

From what I've read there is no such thing as Rubicon springs, just shocks. Some rubis come with softer springs than the sport. You do have to compare the spring numbers to see if they are stiffer than yours. What spring numbers do you have now? It's the last two numerics in the long number on the tags on the springs.

Yes and no. I have never seen a Rubi with numerically lower spring numbers that a similarly doored Sport or Sahara. Now comparing a 4 door to a 2 door is a different story.

my buddies 14 sport came with 60 rears and 18 fronts which are the same as my rubicons. Coils are all over the place so unless you look at the tags it is a hit or miss game.

this is well documented that there is no ryme nor reason behind what gets what coils.

My brand new (built 2/11/14) 2 dr Rubicon with a hard top has 14 front and 57 rear springs.

But I did score a set of 18/59 springs off a Unlimited Rubicon recently...I'm adding a front bumper and winch and want to offset any sag that occurs.

Hey there, I have 2012 2-door sport and am looking at a set of Rubicon springs and shocks. Will it lift my stock height? Thanks!

The shocks won't give you any lift, just a firmer ride and better offroad manners.

As stated above there is no such thing as "Rubicon Springs/Coils" (except the 10A) but a numerically higher number coil will give you a slight lift. Anywhere from ".75-1.75" depending on your situation.

My advice...I went from 14/56 to 18/59 and red Rubi shock on my 2 door Sport. Gained a little over an inch of lift. The ride was much firmer than stock.

I recently installed a Teraflex Performance Leveling Kit and gained another 1/4" in lift and a much more plush ride. Left the Rubi shocks on with the Teraflex. Really nice springs. The Jeep also site level now. It had a slight rake witht he 18/59s.

If you don't mind the little extra money for the Teraflex kit, It is much better.

Rubi take-off shocks are definitely a nice improvement over the stock Sport shocks. I noticed the firmer ride and drastically reduced nose-dive under braking on my first ride after installing a set on mine.

Springs are a joke. No one really knows what gets what and why.

My 4 door Sahara with hard top (but no tow package) came with fairly tame 16's up front, but nice 59's in the rear.

Who knows why....

Great! I got a deal on some 2013 Rubicon shocks and coils. 18 front and 57 rear. He said they were 17 and 59...I'm a bit frustrated but it was still too good of a deal to pass up.

I took a peak under my 2012 sport last night, the springs are 14 front and 54 rear. Looking to install them when I have some free time. Thanks for the responses gents.

It is either length or stiffness (can't remember), but nothing measured.

There is a range of springs for the non 10A JK's. Front springs range from 12 (I think..maybe lower) to 18 (I heard that was a 19 available).

Rear springs range from 54 (I think) to 60 (I heard there was a 61 available).

Basically, the higher the number, the stiffer the springs, and the higher your JK will sit from the factory. But outside of 4 door having heavier springs than 2 doors, and vehicles with hard tops having heavier springs than those with soft tops, what vehicle gets what spring rate is a running mystery.

I'm sure someone else can chime in with the actual range of spring rates. Since I have a 4 door, I don't really know the numbers on the 2 doors.

Those are the last 2 numbers of the spring part#. The lower number, the softer the spring.

Since I was looking for some 18/59's for my Wrangler, here is a link to an eBay auction for reference.

The springs in this auction are 18/60's for instance:

Those numbers are in reference to the spring rate. The higher the number (ex. 14 vs 18 and 56 vs 59) the stiffer the springs.
