Looking for feedback on LCAs lower control arms

I need to replace my lower control arms. I went to the dealer and they quoted me about $590 for each, NOT including labor. While speaking to the guy, I mentioned that I could get acdelco LCAs for a fraction of the cost at rockauto. He said that I will be better off sticking with genuine Toyota because of the tolerances involved with suspension components. If I replace them myself, I could literally save well over a $1000. I am sure the dealer reps are told to not endorse any other brand besides Toyota, so I'm looking to get some opinions/feedback on using the acdelco LCAs vs genuine Toyota.

Thanks!

PS, I put both LCA and "lower control arms" in the title since I figure at least one person out there that could help might not know the difference...that shit happens to me all the time.

 

Just saw my lower ball joint boots are ripped so :bump: for a topic I'm also curious about

 

I went with the Mevotech supremes when I did mine. New Toyota cams and bolts well greased. Worked out well. Check out this thread:
