Skip the full chassis replacement and repair just the rusted driver-side frame section with the Dorman - OE Solutions Frame Repair Kit 999-631. Formed from heavy-gauge steel, it lets you replace a failed center-left frame rail area on select Ford trucks in specific cab and bed configurations. It is a direct-fit replacement for the 2005-2008 Ford F-150, the 2005-2008 Ford Lobo, and the 2006-2008 Lincoln Mark LT (see the Buyer's Guide tab to confirm the correct cab and bed configuration for your truck).

  • Money-saving repair: replaces a rusted driver-side (center-left) frame section instead of the entire original frame.
  • Improved design: re-engineered with better drainage to help prevent future corrosion buildup.
  • Durably built: made from heavy-gauge steel and finished in electrocoated black paint to resist future corrosion.
