I installed the Icon 3 leaf pack 1 week ago. I removed the factory overload leaf. (I have read of people leaving the overload leaf without any problem) I am running them with the factory TRD Sport Bilsteins in the rear for now since my 5100s are on backorder. The ride didn't change much at all. It is more controlled, but definitely not harsh. I can't comment on the load capacity since I haven't loaded it down yet. It was supposed to raise my truck about 1.5", but it actually raised it 2 1/4". I think one reason it raised it so much is because my factory springs were sagging so much. The clunk I had after a hard stop is gone, I'm guessing because I'm not getting spring wrap like I was before. Also, I do not have any noise with these leafs. If you get these or the wheelers, one side is longer than the other. The long side is supposed to go toward the back.
