You may have already posted this, but how much did it cost for your suspension setup?

Awesome....I'm glad you had good luck and your X looks great, I hope they hold up for you. Mine was pretty obvious that 1st or 2nd day that it wasn't enough height. What is your measurement from concrete to wheel well?
I got a set of used V and B springs and have had great results so far. Admitedly, I've only had them on about 2 months. New Rancho shocks too.

Agree. X codes designed for trucks with snow plow application.

I went with X codes and modded B's w/RAS installed a week ago. I have 1/16th under 4 inches between the front bumpstops. 40 inches from pavement to front fender lips (16's - new tires in stock size). I'm also equal on both sides now instead of sagging on the passenger side.
I don't remember exactly but I think the rear is 4 1/2 or 5 1/2 inches between the bump stops and around 41 inches from pavement to fender lip.
I love the ride now....as well as my wife who hated the floating bounce around feeling. The ride is now firm and gives you a nice secure feeling that it will go where you want it to go without crossing lines on either side while trying to get there.
edit - also did Bilstein shocks and Hellwig bars front & rear

twtcad,
Another option if you do not have the money for new, would be to do a modded V. I took my used V codes to a spring shop and he took one leaf off the springs currently on the truck and clipped them together to give you a 3 leaf spring. He said this would help combat any sag since the V codes were used and not knowing what kind of use they have been through. I gained 3 inches from my originals ( 37 to 40 inches at the center of the wheel well lip) I was just about on the bump stop before. Mine did not rub on the inner fenderwell but I am only running stock 265's

That is an awesome truck, cant remember if you mentioned what tire size youre running, 305?
I have a very slightly used set of X codes and a new set of B's waiting to be modded, also just placed an order with caryt for a few parts. My X has 305/70/16 under it now on stock wheels and with only 3/8" clearance to bump stops surprisingly there is no tire rub. Cant wait to get it standing where it should be.

True, I guess I could have worded my post better, you don't need to modify the B codes. But, I don't know of that many that have installed B codes without modding them. CT Performance has tried many, many different variations of springs & shocks on Excursions and modded B codes is what they and others recommend. So, for what it is worth IMO - I would mod the B-Codes. In Addition, as Stewart posted, you need to have a final vision of what you are after for the driving conditions you use it for - which includes tire size, overall ride height and suspension characteristics.
For my application the answer was - 2" hanger kit, V codes up front, Modded B codes in the rear with F-350 stock blocks. A lifted Excursion I can run 50 mph across the field and still fit in the garage.
For those that like a stiffer ride or have a custom front bumper, or a winch the X-codes up front are the way to go.
Bottom line : do your homework and decide what is best for you application

Yep, running 305's on 16" rims, IIRC they are 8" wide. I still would like to change over to 18" rims someday.

Very nice, truck had a newer set of 305's when I bought it in February and I dont want to run a bigger tire nor do I need a bigger tire after I do my spring swap. Those 305's fit in your wells nicely, not too stuffed and still looks capable.
Even with only 80k miles on her my X only has 3/8" clearance to the bumpstops, My 97 F350 Crew had a better ride. Cant wait to get this done.
Thanks for the info
