Please check notes in each part listing to ensure the Differential Bearing is correct for your 1980 TRIUMPH TR8 with a 3.5L 3528cc engine. TIMKEN & NATIONAL are competing brands, and each brand's Differential Bearing may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Differential Bearing fits only certain 1980 TRIUMPH TR8 models.

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

After choosing a Differential Bearing, 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 Drivetrain parts, other TRIUMPH TR8 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 1980 TRIUMPH will not be lost if you switch.
