Detailed Description
This Dorman leaf spring assembly, part number 43-2057, is engineered for rear suspension use where the spring must carry vehicle weight and payload while maintaining ride control. The assembly is listed for 2017-2022 Ford F-450 Super Duty and 2017-2022 Ford F-550 Super Duty rear applications with a 6,345 lb. average capacity. Its steel construction, 10-leaf pack, and included bushings make it a practical replacement for worn or fatigued spring assemblies on Ford Super Duty trucks.
Dorman 43-2057 is a standard replacement leaf spring assembly that matches the application requirements of the original suspension layout. The up-turned eye ends and rear orientation support proper installation in the intended position, while the specified dimensions and load rate help restore suspension function. This part cross-references Cardone Reman 43-2055 for the same application.
What It Is Used For
- Restoring rear ride height after spring sag
- Replacing a fatigued or broken leaf spring assembly
- Improving load support in heavy-duty suspension service
- Addressing uneven rear stance or reduced payload control
- Correcting suspension noise related to worn spring components
Installation Notes and Tips
Verify the vehicle’s rear suspension configuration and load rating before ordering. Confirm the spring dimensions, attachment style, and application notes against the existing part to ensure the correct match for the Ford F-450 Super Duty or Ford F-550 Super Duty. Because this is a rear leaf spring assembly, installation should be performed with the suspension safely supported and aligned to the original mounting points.
Quality Assurance
Dorman supplies replacement suspension components for service applications, and this part is identified by part number 43-2057 for accurate ordering and fitment verification.
