Its sleek design, all-weather performance and legendary reliability set the industry standard.This Part Fits: Year Make Model Submodel 2015 Chevrolet Silverado 2500 HD High Country 2011-2015 Chevrolet Silverado 2500 HD LT 2011-2015 Chevrolet Silverado 2500 HD LTZ 2011-2015 Chevrolet Silverado 2500 HD WT 2011-2015 Chevrolet Silverado 3500 HD LT 2011-2015 Chevrolet Silverado 3500 HD LTZ 2011-2015 Chevrolet Silverado 3500 HD WT 2015 GMC Sierra 2500 HD Base 2011-2015 GMC Sierra 2500 HD Denali 2011-2015 GMC Sierra 2500 HD SLE 2011-2015 GMC Sierra 2500 HD SLT 2011-2014 GMC Sierra 2500 HD WT 2015 GMC Sierra 3500 HD Base 2011-2015 GMC Sierra 35
