Another spring variation question

So I have an opportunity to buy a pair of C-codes off a 2007 F-350 SRW for cheap. I saw pics and it had a service body on it so I assume they optioned for the top single overload spring that was in the picture.
I saw on another thread about someone who took the top overload off of B-code springs and added it to the bottom of the factory front W-codes on their Ex then nodded the rest of the existing B pack and installed it in the rear. I never could find the original post so I don’t know what the final outcome of that swap was as far as ride and extra lift over stock.
I have seen so many variations of spring mods and what-not and don’t know that I have seen any use the C overload to bolster the W spring. Would the outcome not be the same as the B code overload?
Also, how could I mod the rest of the C-code pack to ride smooth but still offer good weight handling for towing?
overall I’m looking to lift about 2-3” at most.

Hey Bass, I was going to respond to your PM tomorrow from work with a bunch of my info, it's been a very busy pre holiday day today.
Quickly, here is a thread where I discuss my rear B codes and the mods I have done to them. https://www.ford-trucks.com/forums/1...questions.html
The link in that thread takes you to the most useful suspension thread on the forum for anyone contemplating modding their suspension, on the first page of that thread you will find my measurements.
I believe that you are bit mixed up on both my front spring mods and what stock springs your EX has. The W codes only came on the fronts of 4X4 F-450s, never came on an EX. I modded a set of X codes with the rear B codes top overload leaf to make a three leaf pack, X codes came on 4X4 Super Duty trucks with the snow plow prep and F-550s.
To get the lift you want from OEM or equivalent springs you will need to replace the fronts, and mod them if you choose.
I'm pretty sure both the B and C overloads would be very close in ratings.
The benefit of the pickup truck rear springs is that they have a few more inches of arch in them, which will provide some lift and give room to squat some when loaded heavy.
My EX with the modded X/B codes and Rancho adjustable shocks has a much more firm ride than when stock, but it never bottoms out now and handles our TT's 1840lb tongue weight. It doesn't go off road, sees no daily driving and gets most of its miles towing the nearly 12K TT on the highway.

Yeah for some reason I thought it was modded Ws that someone had used in the spirit of what you did with the B overload. I’ve read so much I for sure am getting the codes mixed up.....
So with what you said, I was thinking the X codes were too much for what I wanted for the front anyway, so I’m wondering if the top overload out of the C to make a three leaf pack out of some V codes might not be more what I’m wanting to do.
I honestly can’t pass up the $100 C codes so I just need to figure out what to do with the front now.
Modding the C codes with factory Ex rear springs seem to be fairly common. So that info shouldn’t be too hard to dig up. I’m fairly certain I did see that somewhere.....

Something to keep in mind is if they were used with a service body and no air bags then they are likely sagged and no longer going to have the same arch. Basically saying there is a reasonable chance they are junk.

Yeah I've been thinking about that. I'm trying to keep this whole thing under a $1000 budget with shocks, etc so I've got about $700 left. I THINK I can get that done via SD or ATS but it'll be close. I saw these used ones for sale but after finding out it was on a service body, it made me wonder about the springs themselves. We've all seen a service truck sagging in the rear.......
I may just have to save a little more and bite the bullet and get all new. It is probably the best choice anyway, new springs, bushings etc, no worries.

Yes I've been reading all of those threads til my eyes bled. I didn't realize who you were till I sat down at my computer and saw your sig, the mobile version obviously doesn't show that kind of stuff. We've had a discussion like this before when I first bought the Ex and I'm back at it again. I HATE redoing anything. I want it right the first time and will do more research than is probably necessary. I think ultimately I'm just going to go with X/modded Bs from SD or ATS and be done with it. I've got to put tires on it in the next 4 -6 months and obviously want the height set before that happens.
I've gotta make a decision on this and move forward with it, I've gear swaps and engine bulletproofing I also want to do before we hit the road for summer vacation.......

Hello fellow Xcursion owners,
I am new to the forum as of yesterday and I found Ford-Trucks.com by researching the SuperDuty leaf spring swap for EXs. I was about to purchase the X and B code spring kits from SD Truck Springs when started reading about ATS springs and the modded Bs on this forum. With that said what is the general consensus on SD Springs or ATS springs. I have read that ATs is a major contributor to the forum.
I have 03 EX EB 4WD 149,000 miles, 6.0 PS. Factory stock cept for full 4 inch mbpr exhaust. Remote Sinister coolant filter, blue spring kit, volant air cleaner. I personally love the sound, performance, RPMs of the 6.0 and would like to get bullet proofed someday like most 6.0 owners would like.
I would love to get a set of 20 inch wheels and a set of the BFG KO2 AT 275.65s. 343.1 inch tall, about 10.4 inches wide I think. Would love to be able to do it with the X\B code swap. Is it possible. Anyone got any advice or suggestions on any of the above. Will be appreciated. BTW: The SD Trucks spring kit included all four springs and hardware, Hellwig sway bars front and rear. 1.5 inch front 1.25 inch rear I think and Bilstein 4600 shocks. Springs were 43-818 and 43-1261. ATS supplies the 43-1263s I think.
Thanks for all the advice and info I have found so far and thank you for taking time to read my post.

The letter spring "codes" are something that used for their builds, all with set spring weight ratings, arch and travel. Aftermarket suppliers are not and do not always follow Fords specs when marketing their springs, SDTrucksprings X codes for example are actually very close to the weight rating of Ford's V codes. Pretty good difference between the Vs 5200lbs vs Xs at 6000lbs. Even if all things were equal (which I do not believe....) I would recommend ATS for replacement springs, call them and ask for "Junior", he is not only a site supporter but he drives a nice EX himself!

Sounds like a nice wagon, we LOVE pictures around here.........................

With tires at 34.3" I think that you will need 3"-ish of lift up front, but read this awesome thread to verify, it's a must read for anyone contemplating suspension mods on their EX. https://www.ford-trucks.com/forums/1...easurents.html
V codes on a PSD EX should provide about 1.5" of lift, X codes about 2.7", of course they can also be mated with a set of dropped hangers and shackles to get the needed lift.
As you see in the above linked thread, there are tons of options for suspension mods on there big wagons, so give this big jobs plenty of thought before jumping in.

BTW: The SD Trucks spring kit included all four springs and hardware, Hellwig sway bars front and rear. 1.5 inch front 1.25 inch rear I think and Bilstein 4600 shocks. Springs were 43-818 and 43-1261. ATS supplies the 43-1263s I think.
Junior at ATS can set you up with whatever hardware and parts you will need to redo your suspension, he has several very satisfied customers here in the EX family. Give him a call and discuss exactly what you would like to achieve with your suspension mods, he will work with you to get it there.

Thanks for all the advice and info I have found so far and thank you for taking time to read my post.
I think that if you stick around here you find the best group of owners on the web, they can offer all sorts of valuable info and good advice.

I don't know about the X/B set up for sure but it should fit fine. I run the same tire with X/C from ATS and the only thing I needed to do was to remove the front bumper valance.

Hello "I am in Loveland",
I am just up the street a bit. Severance.
Which springs did you get for a bottle of Jack? How big of a bottle? 750 or 1.75?
They have any more or.....?
I browsed through your pics and my EX is red as well. Did you put those lights in your EX? HIDs, LEDs, or? Make of light assembly? I like the bumper as well?
I have been looking for a rear aftermarket bumper with winch mount, swing out tire carrier, keep backup sensors and may be a couple surface mount LEDS and 5 gallon can carrier................for $100. Pretty hard to find? LOL!!!
Thanks

1.75 for the front springs. Buddy bought the truck and pretty much drove it to the lift shop and pulled them off. I did the HID retro myself with morimoto mini's, the light bar is Rigid led, and fog lights are PIAA leds.

Where are you located? I have a full set of Ford V and B codes for sale, all you would need to do is modify the B’s or just get new center bolts and a hardware/ u-bolt kit from Junior at ATS. I have had these in the classifieds here for about 8 months and I think my location has been the reason no one has picked them up yet.
