Hi everyone

I've installed a 2.5" by JKS with fox shocks and also got their j flex control arms (lower front)

Here is what I am experiencing:

Best way to describe is when I am in a drive through filled with cars and you move forward a foot and break, the jeep seems to rock back and forth until it stops ... it's very noticeable

Noticed this when we first installed the lift and based on what I read we loosened all the bolts from the install , shook the jeep front and back , and re torqued to spec on the ground. We have put over 500 miles since we did that and it's still happening

Any idea what could be causing this ? Is this normal at that lift height ? Other than that we are happy with the overall drive

my previous jeep I had teraflex performance level springs and I never had that issue

My JKS 2.5 doesn't do that. If you've checked and double checked all the bolts, then I'm not really sure where to go from there.

I guess the springs are seated correctly?

If it is rocking front to back, I'd look at all the control arms first. If it's side to side, I'd suspect track bars.

Can you post some pics of the lift and maybe somebody can see if something doesn't look right?

Tires are not perfectly round. There is a seam where the tread is put together that will cause a wobble at slow speeds. Put your wheels on a balancer and check to see which one or ones are egg shaped. If there is one that is bad, they can warranty it.
