I currently have a RC 4.5 in lift installed by the PO. It came with the slightly extended lower arms, but the upper arms are completely shot out, I took her offroading a little today and it was just really noticeable how bad they are. I replaced everything else and you could just hear those bad boys clanking around. Anyways, my question is can I run upper adjustables with the RC lowers? Or should I run both sets as adjustable? I could also just replace the uppers with the stock pieces if I shouldn't run upper adjustables and non adjustable lowers. I'd definitely like to be able to increase the caster a touch. But I figure with the adjustable uppers you can only go as short as the stock ones would be? I dunno. Any advice would be appreciated thanks!

 

I cant see why not use adjustable uppers, although if you want them truly adjustable, you really need a thread on both ends, not just one

 

I know there's a lot of hate from years gone by.. But Rough Country has stepped up the game the last few years with their adjustable control arms for the XJ...The latest offerings are very stout pieces and if you're considering a change out I'd get a set of upper and lower for the adjustability...

 

Really eyeballing these cheaper long arm kits like the cavfab 3 link, or the rough country radius arms. Is it even necessary to do on a 4.5 in lift?
