Spring Change... V/B/C/ Icon, so many options
Been reading and talking with quite a few people... yes, I'm one of those people who over-analyzes everything.
We have an '01 4x4 7.3, with a big bumper up front (subject to change). The Ex is used as a family hauler, and we have a small boat, ~3.5k lbs... so not a lot of heavy towing. We are looking for a better ride than what we have, and a slight lift over stock, ie less than 4". I'd like to fit 35's but 33's will be acceptable if its a must.
Currently, the Ex has a Superlift "softride" lift front and rear, and it's too tall and rides rough. This could be in part to the 20's and short sidewall, but the springs cannot be helping. New tires/wheels are going on with the new springs.
Looking to go to either the V/B mod springs, or now considering the V/C's after a lot of reading on here.
The last options I'm looking at is Icon springs, or any other progressive springs.
I'm trying to get more feedback on the following:
1. V/B's vs the V/C's
2. Anyone with feedback who's tried these mods and also tried progressive springs like those from Icon, Full Traction, etc.
3. ATS vs OEM springs
Thanks for all the help. I've read for weeks, these are the loose ends I'm trying to tie up before pulling the trigger.

There are options for suspension. My favorite is the 2005+ Superduty suspension swap. You can fit 35" tire without a lift. After the swap you have more option for suspension upgrade. Such as Carli suspension, Pure performance, Icon, etc. But Carli suspension is my favorite. They have springs for Excursion if you call them.
I did the v/b spring swap then later found out about the 05+ superduty suspension swap. Very happy I did the swap.
05+ suspension, you can upgrade the gearbox with Cardone 27-7621N. Awesome upgrade. Steering effort improves greatly. With 35" tires, I can turn my wheel from lock to lock with the same effort as a stock 2wd Excursion.
My advice,
1st - swap to 05+ superduty suspension. 08-10 if you can find them. Upgrade your gearbox to Cardone 27-7621N. Choose which Carli suspension is right for you.
2nd - Call Carli Suspension, they have springs for our Excursion.
3rd - V/B swap

A conversion is gonna cost you some serious coin. Some VERY serious coin.
Between the V/B spring upgrade (or any similar spring upgrade) and the '05 conversion, there is zero cost comparison. The conversion costs a ton more.

While I've ridden in a few C-rear Excursions, I don't have enough time in one to seriously comment on the B vs C setup. I did prefer the ride of the C rears a little more than my B-mods, however I prefer a stiffer ride in general. With my existing V and B-mod, the rig still floats over bumps and is comfortable, but it's still a bit too soft for my liking and big dips and bumps aren't handled as composed as I'd like (shocks aren't the issue either). I'm not looking for a ride like an unloaded DRW 1-ton mind you.
With the bumper up front and your desire to fit some 35's, have you considered the X code springs up front? I have V's (sourced new) with a 2" drop kit, and my 35x12.50's are close to rubbing. I had to trim an inch off the lower bumper corners to clear comfortably when turning on anything other than flat ground. My wheels had something to do with that, 18x10's with -25mm offset. My old 315/75 16's on stock backspacing rubbed a little bit on the rear of the fender liner. I also wish I had gone with X and C codes instead of the V and B-mod. I'm also surprised at the bit of droop I still get towing the Chevelle on a tandem axle... combined weight of maybe, at most, 6800lbs and the rear still squats about 1.5 - 2".

I have thought about W's, but don't want the ride more firm, and I'm thinking the X's have to be a firmer ride than the V's.
The bumper we have will likely be replaced in the near future, and I won't have a winch.
It's interesting in looking at the springs and weights associated, that the C's have a lower weight rating than the B. Is that correct?

B 320/670, transitions at ~1650 lbs
SRW C 330/650, transitions at ~1800 lbs
DRW C 350/730, transitions at ~1800 lbs
From Ford the cheapest new spring is the B spring, at least when I did my swap.
With my new from Ford SRW C's, I have a slight rake with new V's up front and that's using the stock Excursion block.

PS If I were to do it again, I'd try W springs for the front. The rate isn't much greater but the ride height should be about an inch.

SRW C = 2780
DRW C - 3626
B = 2999
Keep in mind that the stock spring is 2471 lbs, what that means is 2471 lbs per side of sprung mass and most of our trucks should be about 1500 per side with a full tank. Most people would never max out any of the springs...imho.
