Dorman - OE Solutions Leaf Spring Assembly P/N:43-1297
Help the rear of your truck carry its weight and payload with the Dorman leaf spring, part number 43-1555HD, a direct-fit rear replacement for the 2004-2008 Ford F-150, 2004-2008 Ford Lobo and 2006-2008 Lincoln Mark LT. Leaf springs that work properly hold the load of the vehicle and are essential to suspension performance and passenger comfort. See the Buyer's Guide tab for engine-specific fitment.
If your F-150 leaf spring is cracked, broken or corroded, it may need replacing. The same applies if the rear end sags, sits unevenly or bottoms out under load. This rear leaf spring assembly works with its partner on the opposite side, so replacing both rear springs together is recommended to help keep ride height even. Check the product attributes to confirm this is the right leaf spring for your application.
