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.

  • Direct replacement: designed to fit and work like the original leaf spring on the listed trucks.
  • Ideal solution: replaces a spring damaged by overloading, collision, cracking or corrosion, or one that is simply due for replacement.
  • Durable construction: made from quality materials to strict specifications for reliable performance and long service life.
  • Trustworthy quality: engineered, manufactured and supported by what Dorman describes as the premier aftermarket leaf spring provider in the USA.

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.
