I have seen several pictures of Excursion Duallys and have sourced the rear fenders. I have done several F250 and F350 dually conversions in the past but have never attempted an Excursion. I have always just swapped out the axles from a wrecked dually truck to avoid any use of spacers or adapters. Will this same principle work for an Excursion? I'm assuming it will. I just completed doing an '07 coil spring swap into an '00 F250 and would probably go the same rout with the Excursion. The ride is so much better. Anybody out there done this? If so any advice and pictures.

I guess this isn't a very common or popular conversion. Although when you google it there are pictures of a bunch of them. Oh well I guess I'll just have to do some more homework.

I didn't reply because I have no experience, but, if you consider that the Ex is essentially an F-250 with a different body, you should be able to do nearly anything (suspension-wise) to it that you could do to an 00-05 F-250.

Pretty sure the excursion and the f250 ecsb share the same frame. The excursion springs are junk so swap those rear springs at the same time.

Yup. Go with the X/Modified B or X/C springs. I don't actually think B and C are the right codes for the dually version of the springs, but most of those decent spring websites......nevermind, I decided to do the leg work for you. lol While I am not saying you should buy from this site, it's a really good resource for determining spring needs. So, over at SD Springs, it looks like the C codes ARE the dually designated springs and B codes are SRW. However, for the record, either would fit, they just change the ride height, spring rate, etc. Anyway, what's really interesting is that the same code spring changes in dimensions depending on what year you pick. They may all be 3" wide and 25 inches from front to center, but the spring pack thickness and the spring arch changes...as well as the add-on spring changes too. Either way, check THIS webpage out for the basic Excursion spring swap info. HERE is the page which shows what springs go to what vehicles. Just click on the super duty and take a look at the various codes and years to determine what you need/want. For example, the C codes from '02-'04 have an arch height of 8 3/16", while the '05-'06 arch is 6 7/8"....but as it turns out, the C code for '02-'04 is for duallys but the C code for '05-'06 is for SRW. So, takes a little research to figure out exactly what you need, but at least the resources are there.

Wow what a great website. Thank you so much for the info. It will definitely help in making a decision on the springs.

Much thanks to Weatherlite for the great info and link to the spring company. I thought I had it all figured out and that I was going to go with the C code dually springs. Then I watched a couple of videos of guys going with 08 and up springs. The front mounting hanger has to be moved 8" forward because of the longer springs but from the videos they are supposed to give better load capacity and a much smoother ride. You can either reuse the stock hangers and drill new holes or there is company that makes custom hangers just for this purpose that use existing holes in the frame. Anybody heard of or had any experience with this. If I'm under the truck doing all this work anyway I want to make it the best it can be. Any thoughts?

I guess it all depends on what kind of ride you're looking for. I went with what amounts to C codes (I modded B codes for extra capacity and arch) and she still rides great. If you want better articulation and smoother ride, I'm sure the08 and up could be great. One question, though.....what would you use for the front to be able to match the rear's improved ride?

Well I did the front coil spring conversion on my 2000 F350 and the ride and turning radius is amazing so I plan on doing it to the Ex also. I used Fabtech radius arms and Icon progressive rate springs on the F350 but this time I want to go with 4 link arms. They help the ride and stability even more by keeping the camber stable all the way through the articulation of the axle. I have built several wild one off pickups from F150's all the way to a Monster F650 and all in between but never an Ex. I getting older so this might be my last build so I want it to be special and unique.
