I have an '08 JKU Sahara currently with BFG 33s and have a RE 3.5 in economy lift with JKS SB disconnects coming. How important are new control arms? I like to put them off a few months is possible. Although not a DD still used on the highway often.

Thanks Tim

 

it really depends on you. with that much lift, you will most likely feel a little flightiness at highway speeds. some people are okay with it but, if you're not, adding a bit more positive caster will help address that. your kit most likely comes with cam bolts to do this but, i would strongly recommend against using them and just use a set of adjustable front lower control arms to make adjustments instead.

 

Thanks Wayoflife.

If I go with an adjustable front lower can I leave stock front upper on for a while or do they need to be changed as a set?

 

you'll be fine with the factory uppers.
