I am very satisfied with the new bars. They have a wide base to step on. I was concerned about how rigid they would be at the back end of the truck near the back wheels. The brackets on wheel to wheel bars are positioned several feet from the back end and on many bars sag badly when you step On the back end. The manufacture indicated these bars are rated at 500 pounds. They do not sag badly at the back end. Installation was easy but the directions where confusing.

Both bars has small dents in same location out of box. Instructions OK, not great. Not as secure as round tubes I've head in past. They seem to flex more with weight on them that the old round bars too. The step pad had to be thoroughly cleaned out of box but has stayed nice since. Haven't had to endure winter yet.
