I have upper and lower a arms. I got them from AIM. There not bad. I was having problems with my factory lowers rubbing on my bag. The ones from AIM are expensive I paid around 620 with shipping. But I think it's worth it.
be careful of which ones you get my homie got his from chassis tech and they rub his bags hella bad up front.he has to replace the bags every couple months casue he cant seem to get the bags centered correctly no matter what.
