Suspension needs on Excursion for heavy towing

[beamer]

Just curious what is recommended for me to tow a very rare occasion of a 11-12K weight trailer?

Mechanical for power is there, I believe with my 00 EX 7.3 w/ gryphen CTS, 4" MBRP turbo back w/ muffler, AFE Stage II cold air and a BTS trans valve body upgrade cooled by a 31 row 6.0 cooler.

Looking to tow in October from S GA to Bowling Green, KY and back for a car event and want to feel comfort that the suspension is felt to be good to go. I was advised to get air bags for the rear and that Firestone sell an adequate set. What pressures do I run with these? I am sure more than I do in my race cars, lol...


Thanks in advance,
Mike

Check out Roadmaster Active Suspension. They are really popular amongst all the Excursion owners I know that tow regularly. I tried a set on my truck and they worked extremely well. They are also a set it and forget it addition, with no need for airing up and down. Once you install them you are done. The truck handled better both loaded and unloaded with them installed. Here's a link:

Roadmaster Active Suspension, rear leaf spring suspension, simple installation, improve road handling, reduce sway, reduce dangerous body roll on cornering, eliminate bottoming out, eliminate wheel hop, eliminate axle wrap, strengthen the rear leaf s

and:

Riffraff Diesel: Roadmaster Active Suspension Kit

I highly reccomend them.

I highly reccomend them.

I hate that with all the great things I hear about them they won't work with a dually!

These do look like they are what is needed for my circumstance.

I may be at the age of a mid-life crisis, but I don't want to look like it with a super monster skittle ! (My sons high school band refers to the EX as the monster skittle, being a purplish color and all, LOL).

If you look on some of the diesel forums for "CaryT" he has some recommendations. Basically, X-code springs (from an F250) in the front, modified B-code springs (from an F250/350) in the rear and specially valved Bilstein 5100's all the way around. The modification to the rear B-code spring pack is to reuse the Excursion spring spacers (the truck springs just have a small, flat piece of foil/metal inbetween them), remove the top overload spring from the B-code pack and then add the smallest two Excursion springs back to the pack. The other piece is to add a rear sway bar or to upgrade the current rear sway bar if you already have one. Folks generally choose either the aftermarket Hellwig piece or the 30mm F250/350 piece.

For my Ex, I'm waiting for my V/B-codes to come it and I have the Bilsteins from CaryT already. I can't add the Hellwig bar because it doesn't fit with my undercarriege supplemental fuel tank. So, I'm hoping the Ford 30mm piece will fit because it mounts to the axle differently.

Other folks swear by adding traction bars or radius rods to the rear suspension. Other folks have installed the Timbren overload pieces (look like oversized bump stops) and are very happy.

Good luck! Hope this gives you some ideas.

muns53 is right on.

I used the "X" code springs(F-450) and the rears off a 05 F-250 "F" codes, the 30mm rear sway bar, and caryt's bilsteins shocks. It made a huge difference. My Ex sits level and rides and handles so much better.

Look him up, its worth ever penny.

Muns,

Just curious, did you ever try the 30mm Ford sway bar and did it work? I also have a WVO system, tried the Hellwig and no dice. I have a big Racor 1000FH filter housing on mine and it's in the way of the Hellwig. I'd be very curious to know if the 30mm worked for you.

My Ex needs serious help with the wander issue. I've replaced everything up front, sway bar bushings, drag links, steering box, ball joints, etc. I've added RAS. Now I'm thinking I may have to try the V/B code spring swap.
