BlueOx1 I added v codes to my 2002 and it rode rougher,I just bought a 2001 with a 3 leaf setup and Rancho shocks and it rides a lot better than my 2 leaf v codes. I would look at sdtruckspring.com.

Bierman67 I know this is an old link, but if anyone can help...
I have a 2000 4X4 Limited and pull a 32' Jayco double slide. She's getting old, but still runs decent with DP tuner, AIS, straight piped 4"
I am needing new shocks on my Ex and was looking at the 4600 Bilsteins.
I did added a sway bar several years back.
Should I try to upgrade the springs too or should I just live with what I have at this point?
Also, does anyone sell replacement mod'ed springs that can just be dropped in without increasing the height?
Thanks.

1] are you going to tow?
2] are your rear stock springs shot? (Mine probably were not, certainly in better shape than the fronts)
3] what are you trying to improve? see #1. If you plan to tow, I'd say upgrade the springs at LEAST to the B codes, and do a sway bar, no matter what!!! But I'm not a towing guy, talk to those guys.
4] I AM a guy who used to modify one, and only one car (the 1990-1996 300zx) about 100 different ways, with 90 different customers, over a 2 year period. I did get a chance to try a bunch of stuff, and figure out what was changing things for the better, by starting out with the cheap parts first, and then going to the more expensive. From reading everyone's Ford posts on the subject; not just Stewart on FTE or Cary, but as many posts as I could find, I found a common thread, and also compared it to my own experience with the 300ZX. Some 300ZXs came with a rear sway, and some did not. The ones that came with no rear sway sucked at handling, and simply adding one made them a different car.

It's the old Hot Rod addage: you spend 10% of the money to fix 90% of the problems, and the final 90% of the money to fix the last 10% of the problems.

My vote: sway bar first. What did it "fix"? it made much better the straight line feel on the highway, and I KNOW it must have helped the wind-gusts steering the truck around. I did not get a chance to experience gusts before the mod, but I have, in the last month, driven it from San Jose to Sacramento (the Benecia area), and LA (over 152, extreme gusts) and been thru some extremely gusty areas and it handles it as well, or better than my 4800lb BMW 7 series, which is also a good bit smaller and lower.

On my Excursion the FIRST thing I did was the rear sway. I loved it, even with dead front springs, and Gcode rears. I can say, that I then did the dead front springs, and drove that for a week, and loved it just fine, and then modifed (my way) the very decent rear G-code springs I had to B-codes, and still say, the rear sway was the biggest deal.

That is my take-away from this job. If I bought another Ex, and I was on a budget, sway bar is the first thing I would do.

If money were no object, I would follow Cary's advice and get some wider-than- stock, 18" or larger rims, for road use, and get off those 16x8 x32" balloon tires for long trips.

I am not there, yet.

AndrewCJohnston Yes! Yes! And yes! I view this swap as mandatory. Cary's just confident...follow his instructions...add in your own twists for you own preferences. Cary's tried so many combos, hes found the best all around setup.

So I guess we all did it "wrong"

Not sure who Cary was quoting when he said this, but I guess it's "wrong" unless it's done his way, and only his way. No variations. No deletion of slapper leafs, no subtistution of slapper leafs, no substitution of spacer sheets, no use of 1" spacers. Not even sure what about my version he did not like....

But it's totally "not wrong" if you remove the 2" spacer block, which, by the way, has the bump stop arms on it, which is the one thing I would not want to lose.

I did everything you said, except two minor things

what do you find about how I did the job that will cause problems with my setup?

B mod:
Take the two shortest leaves from the Excursion spring packs and add them to the B code spring packs between the shortest leaf and the bottom overload leaf or the B or F codes.
Remove the sheet metal spacers of the B codes and replace them with the 1/8" spacers from the Ex springs.
The centering bolt from the B codes, if they came from a set with the top overloadspring pack should be long enough to hold the modified B code spring packs together. If not a set of longer center bolts will be needed.

Use 2 large C clamps to both hold the spring packs together and for reasembly.
Use a long driff pin to aline the springs as you tighten the C clamps before you install the center pin. Do not use the center pin to align or to tighten the springs...use the driff pin and the C clamps!

You then need to install a 30mm SD rear sway bar F81Z-5A772-AA and properly valved Bilsteins.
I highly recommend the use of dual shocks in front for a Excursion.

AndrewCJohnston mws, nice job. I forgot to mention I too eliminated the b-code overload....but I also didn't reuse the factory slapper leaf. You could remove that and drop down a little more. The b-codes are strong enough to moderate the wrap issues that the slapper was trying to do on the stock setup but the best way to eliminate is to also go to traction bars. Also, the stock ex aluminum spacers soften the ride a little with almost no loss in capacity, so if it feels a little to stiff, swap them back in.

Got a few PMs and my front ride height is good

I guess I was expecting the spring to arch a bit more downward, like my F250, but that does have 3-leaf springs in front, not 2-leaf. The Excursion with the V codes in front (stock rears) has a good stance. About 1" lower in front, right now.

Cary T. and also, Stewart from Ford Trucks Enthusiasts looked at my link and the front V codes look correct when the truck's weight is on them.

I'm in the same boat, still trying to decide.

Made my decision, did the B code mod, but a bit differently

The B's fix so many handling issues...but to fix everything, go B's and traction bars. Have fun! The Ex is the best SUV ever made but it will make you work for it! Labor of love!

check this link for how I did my B code mod. I did not add as much extra height over the stock G codes in the back, but I am at least 2" higher in back than front. The 1" block you mention is a great idea as well. Still might do it. Nice suggestion.
