I'll try and make it there. My folks live in Pleasanton and I'm driving down this weekend so first things first I have to get a good 200 pounds of mud out of my truck from last night and this weekend first lol.

 

Flawless and guys, I just this past Monday with the help of my BIL installed a set of 25K mile X code take-offs (free from a co-worker!). I hate to see anything go to waste and subscribe to the mantra that too much is never enough, so....
I took off the top overload leaf spring from the new B code rears, the ones that have to come off or they will crush the rear A/C lines, and added them to the X code pack. I did add the nylon/plastic sliders (lots of fun drilling those hole...NOT!) to each end of both springs, along with new UHMW (very tough plastic) spacers. I did re-use the U bolts for now, I will order up new ones once the rear gets done and I have all the measurements I'll need.
Before starting I marked a line on masking tape above the wheelwell lip at 39". As soon as we were done, before the test drive so don't know if they have settled any, I measured 42 7/8" to the same line, thats 3 7/8" up from the starting point!
For comparrison AlaskanEx reported about 3" after his 45K X code install without any extra leaves and BostonX73 saw 3.75" adding used X codes with a 1" add-a-leaf, pretty close to my setup and results. The spring chart contained on several threads on this site estimates a 2.9" gain for X codes on a V-10.
It drives fine and is very firm but not harsh (my opinion, I used to drive a '77 Chebby 1 ton as a daily driver) it's nice to hit the dips in the road without them hitting back via the abused bumpstops! Some may feel the ride is too stiff but I bought this truck to tow (heavy) and I don't mind it behaving like a truck. Until I can get the time off work to do the rears it looks like it's going uphill all the time . At this point my plan is to mod the B codes with the bottom two short leaves from the Ex's pack and the cutoff factory "slapper bar" from the EX along with a set of 3.5" tapered blocks, hopefully this will put it back to the original front to rear rake. I wasn't sure about the front shocks and this much increase so I put on the factory Ranchos that came along with the springs for now.
I am planning to start a thread with photos at some point when I get the chance. Hopefully this info (and the comming pics) will help others make their choices on spring swaps. Just for reference my Ex is an '05 V-10 4X4 with 71K miles.

Alright so i'm going to pick up springs from an f250 or f350 that has been parted the guy isnt sure which one. Are all rear f250/350 springs B code or higher load rating? As in i could get B codes or heavier duty ones that would provide more lift. I just dont want to get springs from an f250 or f350 that would give the same lift as my stock excursion ones or less.

Where should i put springs from my excursion front spring pack. On top of the v code springs or on the bottom? does it matter? Sorry for all the questions guys.

 

Nope.

Again, you need to see the door code to determine which springs are on the rear. And that's assuming the previous owner didn't change the springs.

Dunno...I wouldn't have an educated guess unless I was looking at both springs right in front of me.

Don't be sorry for asking, we all want to help and it gets the info out there for others to use in making choices for their rigs.
You won't be able to take a spring from your EX's FRONT pack and add it to the new V codes. Unless you get into cutting them down in length, but why? They are worn out, thats why you are replacing them! The original (and replacement) top spring wraps around the eye bolt front and rear and the bottom leaf wraps around the front eye. There isn't room to fit another layer around the eye and you woulndn't be able to spread the curl enough to get it around the other two already on the eye. As I reported above I used the top overload spring leaf from the new B code REAR pack (single leaf mounted above the pack with a 1" spacer block that can't be used on an EX as it will hit the A/C lines to the rear). I installed this leaf on the bottom of the new X codes, you want it to make full contact with the pack. This will really firm up the ride, in addition to the new firmer ride from your V codes, it will feel more truck-like. If you want the extra bit of lift but not the more firm ride (opinions vary, some may say harsh....) you may want to look into a "leveling kit" from an aftermarket 4X4 supplier. The kits are a few short leaves that get added to the bottom of the front spring pack, they will add some height without much change to the spring weight rating due to their shortness. Still do the V codes of course to get off the bumpstops and a kit would give you the height without the harder ride.
Also about the rear springs, most 250/350 packs are about the same height as the EX's more or less. The truck spring pack by itself won't really give you any lift, they are stronger (higher weight rating) so they will give you less squat under the same conditions but not more lift. The additional height/lift comes from the trucks blocks either 3.5" or 4" usually, replacing the stock EX 2" block with these will add 1.5" or 2" (approx) to your ride height. I have seen several posts here that recommend against stacking blocks! Additional ride height can be obtained from modding the rear spring pack. Typically this involves some combination of the following:
Swap the metal spring spacers from the truck pack with the thicker plastic spacers from the EX pack.
Add the bottom 1 or 2 shortest leaves from the EX pack to the bottom of the new truck pack.
Add one of the middle EX leaves to the middle of the truck pack.
Add the "slapper leaf" from the EX to the bottom of the truck pack, the forward part can be cut off as it's not needed post swap.
As you can see there several incrimental changes available to custom tailor the rear ride height.
I hope this helps some.
