There is an error in the RC 4" lift kit at http://project-jk.com/jeep-jk-write-...ation-write-up

At the section "What you will get with your Rough Country 4" Lift Kit" it should be written "(2) Front sway bar links" (and not "Rear")

Same error in the RC instructions. The tech support at RC has confirmed me this error

 

I did get 2 rear swaybar links. I had to move the factory rears to the front.

 

I did the samething by mistake

Another member had PM me, and he did also the samething...

The 2 RC sway bar links are for the FRONT (not rear) to replace the 2 small Mopar 5" sway bar links.

 

Yeah, 5in is not enough in alot of cases.

 

i have the rc 4" lift and used the rear sway links in the front and new ones in thr back. i took the front ones off when i got rc's quick dicos" for my jeep. the quick disco links and my factory rear links are the same length so i am confused. the ones that came with the lift that i put in the rear are wrong? everything has seemed to be correct. i have had the lift on for almost a year.

 

in the end it really doesn't matter too much as long as you aren't running the stock front swaybar links anywhere. personally i put the stock rears up front since i have the e-disco and the stock rear links have the ball joint on them. Put it this way, however you're running it, if you're not having issues, leave it alone and you'll be just as fine as you've been all this time.

 

Therefore, your rear sway links (RC) are now 10" of lenght. It should be 9" with the stock one. At full flex, the bolt of the sway bar link will rub to the rim (with stock rims) If you have this problem, install the RC sway bar links to the front.
( It should be 10" front and 9" rear)
