My 2007 Dodge 2500 with the Cummins Diesel had some rust issues over the rear wheels. After several body shops discouraged me from repairing them, my trusted mechanic suggested fender flairs. I know it's like putting a bandaid on it, but I took his advice. I ordered them from American Trucks. They were at my home in 3 days. My mechanic installed them yesterday and WOW do they look great! And the fit it simply perfect. I got the screw on flares. It really sets my truck off nicely.
