Both Rubicon rear springs have the same part number?

[ripler]

I changed the title again because I'm an idiot and had the springs backward.

I have the opportunity to buy what I'm being told is a Rubicon take off suspension. The spring numbers are as follows 3589AA, 3589AA, 3659AD, 3660AD, I can confirm that they are the same, he sent me pictures of both shocks in the same picture both with the same number. He said they are off of a JLUR, with the one-touch roof, no steel bumpers and with towing package. I looked at the shock matrix and couldn't find this combo. I thought that all 4 springs had different numbers.

Do these part numbers make sense that they are actually off a Rubicon?

What about the shocks with the same numbers?

I will be putting this on my wife's JLU Sport S with hardtop, any speculation on how much lift I should expect?

@AnnDee4444 has a great spring # resource here
https://www.jlwranglerforums.com/fo...gs-suspension-information-chart-matrix.66591/
I don't see any Rubicons listed in that chart than include an 89 spring, the Rubicons do have the 59/60 in quite a few configurations. The chart may not have the most recent spring sets, not sure about that. It's possible newest Rubicons have shorter front springs to help w/ caster issues so maybe??

@blnewt I had the spring location backwards, the same springs numbers are from the rear springs.
I did look at the spring matrix and that's why I have some concerns. If I installed these on the wife' JLU would I have any issues? I could buy the take offs (he's asking 200.00) and then just buy a new spring for 70.00 with a slightly higher spring rate for the rear passenger. Or my other option is just to buy a spacer lift since she is only going for looks and not off road performance. I just figured if I was taking everything apart just to do a spacer lift I might as well just change over the suspension to a Rubicon.

You may want to check to see what you have now vs these numbers. I had 3587 and 3588 in my Willys and picked up a set of 3591 and 3592 in the take offs I found. It ended up at 1 3/4". I also did TF spacers in the front with the Rubicon springs as others have to level it off.

I passed on the suspension, I think the spring rates are on the low end for a Rubicon. Having the same spring numbers on the rear was throwing me off. I wonder if it was a mistake from the factory.

Keep your eyes open and something else will come up. I ended up picking a set up from a member and the front was two steps up and the rear was four. I think it was a $100. Mine had the shocks already and I have a spare set.

Both of my stock rears are 3591AA, and both of my stock fronts are 3662AD. So having both sides the same is an oem config.

I chalk it up to having the 2.0T with the eTorque battery. I also have tow pkg, dual top, and steel bumpers.
