• Description:

  This is the genuine Ford rear leaf spring assembly for the 2017-2020 F-150, cataloged by Ford under part number KL3Z-5560-A. The leaf spring mounts between the frame and the rear axle to support the truck's load, control ride height, locate the axle fore and aft, and absorb road and payload inputs so the rear suspension maintains proper geometry and ride quality. Over years of service and heavy or repeated loading, leaf springs sag, lose arch, crack a leaf, or develop worn spring eyes and bushings, which shows up as a rear end that sits low or leans to one side, reduced load capacity, a harsh or bottoming ride over bumps, clunking or squeaking from the rear, or uneven rear tire wear. Replacing a fatigued or broken spring restores factory ride height, load rating, and axle location. This assembly is engineered to the F-150's original spring rate and mounting dimensions for a correct fit at the frame hangers, shackles, and axle U-bolt seat. Springs are frequently replaced in matched pairs so both sides carry equal load and the truck sits level; inspect the shackles, bushings, U-bolts, and center bolt during installation and replace worn hardware as needed. Always support the vehicle safely and relieve axle load before removing the U-bolts, and torque all fasteners to Ford specification on reassembly to preserve ride height and handling.
