I have a Teraflex 2 1/2 " inch coil lift with the stock rear track bar.
I am running front lower and rear upper TF adjustable CA's
The rear diff. is angled up to keep the driveline at a good angle (2 door)
The rear coils have a slight bow to them and hit the rear trackbar.
Not sure whether to shorten the upper rear CA's to drop the diff and reduce the bow and increase the driveline angle,
or use Coil Correction Wedges to reduce the bow of the coils and stop the contact with the rear TB ??
It's a 2012 2 door Rubicon

 

I used the wedges and haven't had an issue since. This was in a 4 door with stock arms. Don't know if that will make a difference.

 

the correct way to do it is to cut the lower spring perches off and reweld them in the correct place for the axles new angularity.

 

also...the wedges work pretty good on the street but off road with your suspension twisted up the wedges will pop out,i have seen this happen first hand more than once but you may be able to round up some kind of upper coil retainers, although i have not seen anyone do it personally.

 

I have rk arms and ome coils. I had this problem too. I moved my frame side mount back some and put in the jks coil perches. Problem fixed.

 

Thanks for the replies, anyone else have any input
