Detailed Description
This Dorman leaf spring assembly, part number 43-170, is intended for front suspension use on 1953-1956 Ford F-100 and 1953-1956 Ford F-250 applications. The spring is built from steel and uses a seven-leaf construction with a 1,050 load rate, making it a direct service part for restoring suspension support and payload control. The 43-170 part number is also referenced in interchange listings as 43-170DAY and TBAA5310A for the same application.
For Ford F-100 and Ford F-250 trucks, this assembly provides a standard replacement format with bushings included and a front axle orientation. The listed dimensions and attachment style help confirm the correct match before installation, especially on vehicles where spring arch, pack thickness, and end configuration must align with the original setup.
What It Is Used For
- Restoring suspension support when the original leaf spring has sagged or weakened.
- Addressing uneven ride height caused by worn spring packs.
- Improving load-carrying stability in front suspension service.
- Replacing a damaged spring assembly with the correct attachment style.
- Correcting ride control issues related to tired or fatigued spring leaves.
Installation Notes and Tips
Verify the vehicle year, model, and front suspension configuration before ordering. Match the spring dimensions, leaf count, and end attachment type to the original part, and confirm that the application does not require axle modification. Mounting hardware is not listed as included.
