Everywhere I look I can find lifted rear springs for a Bronco but can’t find factory height springs. However I do see them for F-150 (4x4 are 3” wide like bronco). Was wondering if these were the same springs. I would imagine they fit but are they the same spring rate? If anyone has any input I’d appreciate it. I just put new springs on the front and want to do the same for the rear, just new factory height springs.

Thanks

@AbandonedBronco installed what looks to be the same as @BlueBox posted above.

General Spring is where I got my leaf springs from. Been super happy with them.
And yes, 42-813 is the part number for Bronco springs.

For what it's worth, the front mount hole is a 16mm bolt and the rear shackles are both 14mm bolts, in case you need to replace them. I can't remember the lengths off the top of my head, but can go measure if need be. They're usually rusted if really old and need to be replaced.

BroncoGraveyard sells a leaf spring bolt kit which I ordered, but to my disappointment they supply it with a 5/8" bolt, which is not big enough. 5/8" is 15.875mm, and the difference between 15.875mm and 16mm is enough for it to rattle. I ordered two 16mm bolts online and swapped them in and it was much more snug.
Also, always get 10.8 bolts. That's the metric equivalent to grade 8.
