Detailed Description
Leaf springs carry vehicle weight and payload while helping the rear suspension keep consistent geometry under load. Dorman 43-817 is a standard replacement rear leaf spring assembly for Ford Ranger applications, using a steel spring pack with black bushings and Berlin eye ends for direct suspension service. The part number 43-817 is listed for 1983-1985 Ford Ranger rear suspension use, making it a focused choice when replacing a worn or sagging rear spring on these trucks.
What It Helps Address

- Uneven ride height on a Ford Ranger
- Excessive rear suspension movement under load
- Noise or looseness related to worn spring bushings
Installation Notes and Tips
Verify axle orientation, spring length, arch, pack thickness, and bushing style before installation. Confirm the vehicle build date for 1983 Ford Ranger applications, since the listed fitment begins from 1/83. Inspect spring mounts, shackles, and related suspension hardware for wear before replacing the leaf spring assembly.
