- 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.
