Please check notes in each part listing to ensure the Harmonic Balancer is correct for your 1981 CHEVROLET K10 SUBURBAN with a 5.7L 350 engine. DORMAN & ATP are competing brands, and each brand's Harmonic Balancer may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Harmonic Balancer fits only certain 1981 CHEVROLET K10 SUBURBAN models.

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

After choosing a Harmonic Balancer, 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 CHEVROLET K10 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 1981 CHEVROLET will not be lost if you switch.
