Well, I called Total Chaos and quizzed them on their Upper Control Arms (UCA). What I found out is that they are NOT heat-treated! Personally, I think that not heat-treating 4130 is simply dumb as you end up with a part that isn't much stronger than 1020 mild steel with brittle weld areas (and it's more expensive to boot). Also, still not to sure about the "1 inch uniballs". The gentleman on the phone said they would last thousands and thousands of miles but the one thing that would wear them out is dirt getting in the ball and that they should be wipped down at every fueling.
I can deal with maintenance on the balls but no heat-treat... I'll pass.
