Please check notes in each part listing to ensure the Supercharger is correct for your 1985 CADILLAC FLEETWOOD with a 4.1L 250 engine. Special restrictions like "California only" or "with sport package" may indicate a Supercharger fits only certain 1985 CADILLAC FLEETWOOD models.
Clicking a "More Info" link will display a picture and/or other details about that Supercharger in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Supercharger, 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 CADILLAC FLEETWOOD 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 1985 CADILLAC will not be lost if you switch.
