Please check notes in each part listing to ensure the Timing Cover Seal is correct for your 1983 GMC C1500 SUBURBAN with a 5.7L 350 engine. L & S AUTOMOTIVE PRODUCTS, SKF, VICTOR REINZ, & DNJ ENGINE COMPONENTS are competing brands, and each brand's Timing Cover Seal may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Timing Cover Seal fits only certain 1983 GMC C1500 SUBURBAN models.
Clicking a "More Info" link will display a picture and/or other details about that Timing Cover Seal in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Timing Cover Seal, 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 "Find More Parts" to find more Engine parts, other GMC C1500 SUBURBAN parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1983 GMC will not be lost if you switch.
