  Kit Frame Rail Replacement

• Description:

  This Genuine Ford ML3Z-5D059-B is the left-hand frame rail end replacement kit for 21-25 F-150 Crew Cab and SuperCab models. The kit ships as the boxed steel rear-section frame end that splices to the surviving forward portion of the original frame rail, restoring the structural rear-frame geometry needed to mount the rear bumper, hitch receiver brackets, rear leaf-spring hangers, and bed support brackets after severe collision or corrosion damage. Body shops install this kit during major rear-end collision repair where the original frame is bent or kinked beyond factory pulling spec, during corrosion-driven frame rebuilds on heavy-salt-region trucks, or after a heavy trailer pull-through has overloaded the bumper hitch and twisted the LH frame rail beyond reuse. The job is a certified frame-shop task requiring the original damaged section to be cut at the OEM splice line, the new section trial-fitted with rosette welds at the manufacturer-specified plug-weld locations, and a full continuous fillet seam run once the rail is aligned to dimensional spec. Final corrosion protection on the repaired joint is critical to preserve the original frame rust warranty profile.

• Notes: Included with frame assembly.
