I had the same bars since 1988. They have been on 4 different vehicles. They have carried skis, cargo boxes, canoes, kayaks, lumber, you name it I've carried it. They are still straight as an arrow and no rust. I also bought the 65 inch square bars and they are still the same. I've overloaded them and they still look new. If I could add a photo you would see what I mean. The Thule rack systems are the best in the business, period.
