Hey guys, I've recently purchased a 2001 Limited Excursion with a V10 and its 2wd. I bought it as a tow rig to pull around my rock crawler. Its super clean and everything runs well. There is only one problem that I have so far. When I loaded up my rock crawler onto the trailer I noticed (when pulling) that the rear end seemed a little "floaty". I've had some friends tell me about putting F350 springs in the rear to help get rid of this. I also heard about an air bag suspension too. Just wanted to get everybody's opinion. Any help is greatly appreciated!

Change the springs and add Roadmaster active Suspension. Here is there 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

 

I lifted mine and added the RAS later, it made all the difference towing and even unloaded!

 

Welcome! Your going to love the Excursion!!!

 

Welcome! I have 3 things to tell you:

If yours has the towing package, you have a factory rear sway bar. If not, then one is recommended. Stock or aftermarket, I think aftermarket is hellwig. Apparently it can feel quite floaty without one. Mine has the tow package so I've not ridden in one without.

Second, the stock springs were tuned for people comfort, not towing, regardless of the rating on your receiver. Swapping them for springs off a superduty with B code rear springs, as found on the white sticker on the door jamb, is a good fix that will give you another inch or two in the rear and will stiffen up the rear a little for towing.

Third, the stock shocks were weak. Most forum members go with bilsteins or rancho 9000's.

Alternatives to these exist in the forum of the roadmaster active rear suspension, which is really just a coil overload spring that mounts horizontally, and an air bag system. You can add either of these to the above modifications as well. The forum is pretty well split on what exact combination of modifications results in the perfect balance of not too stiff a ride but not floating and bottoming out while towing. But the above should give you enough to do some informed searches so you can see what people say about both mods. Your searches may turn up landyot radius arms, but you should know they are no longer in production.

Oh, and obviously keep those rear tires pumped up. 55-65 psi while towing. Make sure you have load range E's as well. occasionally you will find a previous owned threw some lower capacity tires on there.

congrats on the purchase.
