I have a 2014 FX4 in need of passenger side rear leaf replacement due to sag.
I was wondering if all leafs from 09-14 are the same other than 2-3 leafs pack, and is 2WD and 4WD the same spring rate?, or specifically can i use A 2015+ set in either @2WD or 4WD?.

 

What I suggest is to look up Ford OEM parts online and with the 2014 FX4
you'll see 5 different springs (ID) but all '09/'14. See what the ID is to get the
correct spring, but would replace both with whatever spring you decide upon
as with just one, I'm certain the truck would not be level, just from age/use.

You can always look at aftermarket suppliers, e.g. RockAuto to compare, but
shipping would be costly.

Just put some Monroe load leveling shocks for less than $100 and be done with it. Gas shocks with spring overload, have them on my 2013 Screw 4wd.

 

I know for the fact that 2019 springs are shorter than 2011 springs, the 2019 springs also have a large bolt where it attaches to the shackle. So with that being said i would say 15+ springs will not work.

04-08 might work but i cant confirm.

Any 09-14 will work.

04-08 F150 rear leaf springs are also shorter than 09-14.

 

Thanks for the response guys.
So it looks like only 09-14 will do for me, I just need to figure out which of the five Spring Packs is the correct one for my truck.
I do have an airbag kit and an add a leaf kit available, along with new shocks.
I’m undecided which system I will use.
I would rather correct the problem first.
the truck is going on the hoist in a couple of days just to make sure nothing else is bent or broken.
