Preparing for coil swap.

Hello all!

Well I got a good deal on a set of 17/58 coils, which I plan to install replacing my current 14/55s.

I am expecting about 1” – 1.5” out of the coils swap……sound about right?

My main question is…..since this is my daily driver, I cant afford to leave it unuseable after the weekend install…..are any other parts that are absolutely necessary (other than the 4 coils) to get it back operational????

I Don’t plan on wheeleing short term, so if say shock length isn’t ideal, or brakelines are a little snug but not really in danger, I can do this…..Im just concened of any required part that could render it undriveable after the coil swap if not also replaced now.

Thanks in advance for any input!

SP

Nope .. Should be a simple swap.
Maybe ... Just maybe longer swaybar links up front but that it.

just make sure you loosen the break lines before removing the sway bar links.. you will likely need to recenter your steering which is very simple

May be a dumb question but how would he know about the sway bar links?

The sway bar should roughly be parallel to the ground. If it's too far off after the swap, he'll want to get longer (or adjustable) links. Not an emergency, but it should be done for on road stability.

Don't you mean perpendicular (up and down)?

No he means the ends of the sway bar not the links

The rear will prob be fine. At 2" lift the front links are super short. What he can do it run discos that are adjustable up front or a stock set of rears -up front.

factory stock coils of any size will/should not require extended sway bar links because they are in fact stock coils and the stock jeeps only have one size of sway bar links no matter what coils they are equiped with.

One of our very knowledgeable Members, went from 14/57s, to 19/60s. He said that no other changes, were required!

Yep pretty simple swap. I did coils and Rubi shocks at the same time. No extra parts needed. Just read up and ensure you have all required tools and a good torque wrench. Then follow a good set of instructions and have at it.

I did the spring swap from 13/55 to 18/60's and I agree that these are all stock jeep parts but I gained over 2 inches front and back and the stock swap bar links were way off and I put a set of teraflex quick discos that were twice the length of the stock ones to correct the front but rears were still good so my question is why if all stock then why were fronts so off. Could I have left fronts on?

I think what we see here is that although all of these springs are "stock", they are being put in to different applications. As such, we are getting slightly different results than intended by the factory. By putting the 18/59 or 19/60 on a sport 2 door, we are using springs intended to support a lot more weight (4 door) at the factory ride height.

So basically, we are putting a small 1" to 2" spring lift on when going up from say 14/55's. If you actually get 2" of lift, you have to consider it to be no different than an aftermarket 2" lift other than the spring rate might be a little lighter, which is probably a good thing.

A 2" lift typically needs to look at and evaluate the need for bump stops, sway bar links and even shocks (consider extensions to keep proper down-travel). These may not be needed, but should be looked at.

Yes, they are stock springs and you might be ok, but there are areas you should pay close attention to when going from the lowest numbers to the highest numbers, especially if you are going to wheel with your rig.

My springs came off a 2014 jkur and also put the Rubi shocks on and everything was good except front links. Are stock links on unlimited longer than jk links? My jeep handles good and flexes good, better than before

Same ... The rears should be fine. Fronts should be changed given their short length. A set of stock rears work great in the front around 2-2.5"
Having the front swaybar higher then parallel is ok, as long as there no interferences. My links are prob 20* over parallel.

I put the 0-3 teraflex discos on and its almost parallel, they are twice the length of stocks and with cut fenders or new flat ones I feel I could fit 35's. Am I right in my assumptions?

Might be a little tight but doable.
