I got some use boxed Procomp LCAs look beefy as hell but my I am pretty happy with the way my XJ flexes now even with the stock lowers so will these be at least the same?(or better)I like the flex I got now but wanted something more heavy duty for bashing on rocks.Thanks in advance and there are some pics of them in my build if you want to see the arms

Well, just about any aftermarket control arms are better than stock. But, if you want beefier you can't just beef you control arms. The mounts on the unibody are pretty weak.

Kinda what I thought.Would it be detrimental to use these before beefing up the mounts?

No. Use them and get you some lower mount skids.

Thanks man,I got some jcr skids just got to get them welded on

Ya. I actually have some pro comp lower arms sitting around I need to get on too.
