truck stuff

I have a 2003 avalanche I had a 6 inch rough county lift put on it. Since then I have been to 5 different front end shops several ball joints broke and A-arm backing out of my drive way . I cant keep tires on it so far it has been though 2 sets of tires that are 2,200 a piece NO ONE can get it to align. Rough county will not stand behind there stuff terrible customer service. The truck has never drove right hard to keep it on the road. I cant get any help from them I'm sure someone else has had this problem, if anyone knows a way out of this mess please let me know.
