There are aluminum pans that prevent rock damage and such but I went with the McGuyver and it held up well. Also jacked up my 02 several times and had no issue. It recently sacrificed itself when I pulled over a parking barrier I didn't see (sun glare and fairing width). Only the pan was damaged, another on order. My original aluminium pan I would remove before jacking the bike, but still was little issue, it surely would not take the jack without crushing.
