Fitment and application details

This leaf spring assembly is specified for the rear suspension of Ford F-350 Super Duty trucks from 1999 through 2007. The Dorman 43-1265HD matches the listed application with a 10-leaf, heavy-duty aftermarket design, 4.47-inch pack thickness, 5.375-inch arch length, and 30.25-inch length B. For search relevance, this part is commonly referenced as a rear leaf spring assembly for Ford F-350 Super Duty 1999-2007, and the part number 43-1265HD is also used in OE Solutions interchange listings.

This part cross-references Dorman OE Solutions 43-1265HD and aftermarket interchange 043-1265-00HD for the same application.

What this part helps address

  • Sagging rear ride height from worn leaf springs
  • Reduced rear suspension support under payload
  • Uneven rear stance caused by fatigued spring packs
  • Excessive rear-end bounce or instability on rough roads
  • Loss of consistent suspension performance in heavy-duty use

Installation notes and tips

Verify rear suspension measurements and match the listed attributes before installation. Replace in pairs when servicing both sides of the rear suspension, and confirm that the up-turned eye ends, bushing configuration, and pack thickness align with the vehicle’s existing setup. Because this application is listed for the rear of the Ford F-350 Super Duty, confirm axle and spring-seat condition before final assembly.
