Please check notes in each part listing to ensure the Outside Mirror is correct for your 2008 GMC SIERRA 1500 SLT with a 5.3L 325 OHV engine. VARIOUS MFR & SHERMAN are competing brands, and each brand's Outside Mirror may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Outside Mirror fits only certain 2008 GMC SIERRA 1500 SLT models.

Clicking a "More Info" link will display a picture and/or other details about that Outside Mirror in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Outside Mirror, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button, or click on "Find More Parts", to find more Body-Exterior parts, other GMC SIERRA 1500 SLT parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 2008 GMC will not be lost if you switch.
