Best Answer:Hi Bruce, You missed mentioning what type of Sierra, is it 1500, 1500HD, 2500HH, 3500HD? You may check the fitment of the part manually - please enter your vehicle’s year, make, model, sub-model, and engine type, and type the part's name in the search box. Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
