Detailed Description

This Dorman leaf spring assembly is built for rear suspension repair on select Ford trucks from the 1970s. It is listed for 1973-1976 Ford F-100 rear, 1976-1979 Ford F-150 rear, 1973-1979 Ford F-250 rear, and 1975-1979 Ford F-350 rear, with fitment notes that include 5-leaf and 4-leaf/1-leaf configurations depending on application details. For buyers searching for a rear leaf spring for 1973-1979 Ford F-250 or a replacement leaf spring assembly for a Ford F-150 rear suspension, Dorman 43-569 provides the specified dimensions and attachment style needed for the listed vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Rear sag from worn or flattened leaf springs
  • Reduced payload support in the rear suspension
  • Excessive bouncing or unstable ride height
  • Uneven rear stance on Ford truck applications
  • Noise or looseness caused by aging spring bushings

Installation Notes and Tips

Verify spring width, arch length, pack thickness, and end attachment type before installation. This assembly is for rear axle use and does not require axle modification. Bushings are included, while mounting hardware is not listed as included. Confirm the vehicle serial number and spring configuration for 1973-1979 Ford F-250 applications, since one fitment note applies only from serial number Y20001.

Quality Assurance

Dorman supplies this leaf spring assembly as a standard replacement part built to match the listed application requirements for rear suspension service. Review the fitment notes and dimensions against the vehicle before ordering to ensure correct application.
