Superduty spring swap, which pack?

Sorry if this has been covered somewhere, but I've been reading spring threads for a couple days now and I'm dizzy with all the conflicting information out there.

Got a 2003. Use it for offroading and backcountry camping, rarely if ever for towing. Pretty sure it's the stock suspension. Which rear spring packs should I be shopping for if I want about 3 more inches of nice flexy travel and a plusher ride in the ruts and rocks?

...and another good thread on the pro comp springs: https://www.ford-trucks.com/forums/1...p-install.html

holy bejesus the chatter that comes out of my head sometimes. lmao

that might be one of my more complete explanations, maybe the mods could move that one to the tech folder and save me from writing doing the A-Z write up that i get asked for that I never seem to get around to. I am better answering questions then writing manuals.

you should be avoiding the ford code setups ( ie Mod B ect ) if that is what you are looking for.

from my point of view the typical Mod B swaps fall short in several areas. spring rate is too high, they do not eliminated the block and they certainly are not “flexy”

back in the day they were a great junk yard solution when the only aftermarket spring was full custom and high dollar.

nowadays you can build a better suspension for less money then using ford code springs.

fwiw the so called information that is conflicting is opinions rather then actual information and since everyone is entitled to an opinion they are bound to vary which leads to the confusion. if you are looking for facts then ask and I will do my best to give you the data without any opinion, which is my normal MO.
( yes i have opinions but I prefer to share my information )

currently traveling abroad but when I get home I will try my best to sit down and fill in the blanks on that post to make it as complete as I can.

that may be the bulk of it but as always the devil is in the details and I see that alignment wasn't discussed, cant be a complete suspension conversation without talking about the steering system and alignment.

if you are asking about the 22210 and 22415 procomps then the answer is, center of hub to bottom of fender lip measurements are:

procomp setup
fronts 27”
rear 27”

stock
front 23
rear 24

if you are asking about something else then you will need to be specific

Nope, that was the question. Appreciate the input.

That other thread Nicmike linked really should be in the stickies, that's a good one. Looks like Procomps with the sway bars pulled is where I want to be.

What are folks doing for bumpstops with that block pulled? Just stick something between the frame and leaf spring?

I like the PMF. air bag tang top plates as a bump landing pad.

i dont have the dimension but easy enough to measure, you will need to lower the bump down to get the timing correct.
Airbag Tang Ubolt Top Plates

you want to stop the up travel when the spring is flat. tie a string across the spring mounts to simulate flat and measure the gap between the stop and the bump, you need a spacer that tall
