im looking to replace my front upper control arms on my 4 door rubicon. i have a 3.5 inch kit on now and i think i need a few more degrees of cam on the axle. does anybody have any suggestions.

 

I would personally go with the adj front lower control arms- you could set your caster with those just fine-

 

I'm not sure there's enough adjustment in the front upper control arms. I would get adjustable lower control arms.

 

Uppers are less expensive, lowers offer a better range of adjustability. The Currie uppers are the ones I see posted about that can adjust short enough without needing lowers also. (others may work, I just haven't seen any posts on them...)

I know Mr. Northridge sells some kits with adj uppers only, so that may be a good place to check.
