Hi all,

I have a stock ‘16 JKU Sport. Friend of mine gave me his barely used springs and shocks off his ‘16 JKU Rubicon. I plan to swap them out and all the research says no problems. I was verifying what was in the box and found some rear Link Stabilizer Bars for the rear in the box. I compared them to mine and these are shorter than what’s on my Jeep now. Not sure if I should use the ones in the box or leave what I have on there. Any tips?

 

I would not bother swapping the coils as they may be the same you already have. There are tags with numbers on the coils that tell you what you have. You might want to compare as the rubicon does not have a special suspension like many people think. The only real benefit is to a 2 door soft top jeep that will see some actual lift from putting on JKU hard top coils due to the higher coil rate. A lot of lifts will put the factory rear sway bar links on the front since they are longer and give you new longer rears. I suspect you are looking at a front link, not the rear. Compare those to your factory fronts.

 

I started the job and found the front links are the same length as what was in the box, so you’re right on there. The spring compressor I rented doesn’t work for this style, so that may be the deciding factor for spring replacement, at least for today. I’ll double check the part numbers though. Thanks man.

 

You don't need a spring compressor, just remove the shocks and sway bar links and you will be able to remove the coils.

 

So, I ended up replacing all the shocks. Front springs were the same. Back springs have different part numbers and the ones I was given are more expensive, but not sure what the difference is. Will do some research and see if they’re worth doing for the back only,...

As for the ride, it’s bouncier on the road and not as stiff. Hit some pot holes on gravel, and it was smoother than the stock shocks. I think it’ll feel better on the trail. Overall, slight upgrade, but glad it didn’t cost me anything other than an afternoon wrenching,

 

I'll swear up and down the difference you think you feel is just placebo effect. It's not worth your time at all. I realize it's free.....and would reiterate it's still not worth your time.

 

The different spring numbers are slightly different lengths. What they equate to under the weight of the jeep isn't much. I think I picked up 3/16" by going up a few coil numbers-- on a stock 2dr with no added weight. Factory coils still fatigue quickly though so I went aftermarket for my 2010. Now....for my 2016 I've got an extra set of coils in the garage with 3k miles on them whereas the jeep has 45k miles. I'll replace those when they start to look a little low.
