This is a pair of Husky 57791 mud flaps that fit 2007-2014 Chevrolet Silverado trucks. My friend had these and he never installed them on his 2008 Silverado. He's since sold the truck and these are up for sale. According to Husky they fit: 2007-2013 Chevrolet Silverado 1500 2007 Chevrolet Silverado 1500 LT 2007 Chevrolet Silverado 1500 LTZ 2007 Chevrolet Silverado 1500 WT 2007-2014 Chevrolet Silverado 2500 HD 2007 Chevrolet Silverado 2500 HD LT 2007 Chevrolet Silverado 2500 HD LTZ 2007 Chevrolet Silverado 2500 HD WT 2007-2014 Chevrolet Silverado 3500 HD SINGLE REAR WHEELS 2007 Chevrolet Silverado 3500 HD LT SINGLE REAR WHEELS 2007 Chevrolet Silverado 3500 HD LTZ SINGLE REAR WHEELS 2007 Chevrolet Silverado 3500 HD WT SINGLE REAR WHEELS
