If they are the chromoly ones they should be OK. And for the ball joints although they do get sloppy after a short while they can be run like that for years and years . For $300-$400 its a good deal but if they are more than that Id go with some other brand. One the plus side they are crazy adjustable to any geometry you want.
I ran them and liked them. You can upgrade the heims when they wear out. They do honor their warantee. I broke one and they sent me a new one. I would buy them again for sure.
