I want to swap out the lower control arms on my 05 stang gt, who is a reliable company? and should I also change out the upper control arm? any help on this would be great.

 

Try doing a search on the forum for UCA. You will find a TON of information.

There are a lot of good LCA brands. I think the best is BMR, that is who I'd suggest. Their quality and customer service are the best in the business. Several of our forum sponsors carry them, or you can get 'em straight from BMR.

The lowers are the main weak link. However, the aftermarket uppers are better than stock. It all depends on how much you'd want to spend. In my opinion, the lowers are a "mandatory" upgrade on these cars. The uppers? Not as important, but definatley worthwhile.
