2024+ vs 2023 Rear Leaf springs

[Dan13b20]

Does anyone know what the differences are between the 2019-2023 leaf springs and the 2024+ leaf springs? Thank you in advance for any info.

You could try looking up the part #'s on Ford parts website to see if they're the same, the shock placement were changed from the earlier years so right there is a small diff also fwiw the front suspension is different between the 5th & 6th Gen so there's more changes made, granted the rear susp is simpler than the front setup so hopefully for you it turns out it can be swapped.

Ya the stock numbers are different 2019-2023 is KB3Z 5560 F and 2024+ is MB3Z 5560 DX, problem is there is no part description or specifications given and of course the generic little picture does not help you see where the differences may be.

The bds rear shackle kit for a 5th gen fits our trucks. I have it on my truck as a 1" rear lift so the leafs are at least the same width

we have a composite overload spring, that’s that only difference i’ve seen physically. in sure the spring rates are different because my truck now rides almost as nice my my 2020 with tremor leafs. (because the 2020 fx4 leafs were trash)
