Lifting 03 Expy
There are several spacer kits available, Daystar, EZ-Lift, etc. Most are really made for the F-150, so they are front only kits, since the rear of the F-150 is a different set-up than the Expy. The Daystar has a 2" front and rear kit, but it is a different type of spacer kit which requires diassembling the coilover and putting the spacers in between the spring and the cup.
The Truxx kit is the only kit I know of that was made specifically for the Expedition, and it is the biggest lift available.
So basically, if you want front and rear the Truxxx and Daystar are your only options, unless someone else has come up with something since I was looking a few months ago. The Truxxx is a little pricey compared to the Daystar, but I got mine a lot cheaper than what is listed as MSRP on the Truxxx website. The Daystar is less but it requires a lot more in installation. If you can do the work yourself the Truxxx install would be WAY easier. If you were to pay someone to install the Daystar kit you would spend more than the Truxxx kit anyways.
There are pics in my gallery of what it looks like with the lift and 33's.
If you really want to go big, the only full suspension lift I know of is made by Rize Industries in El Cajon, CA, and I'm not even sure if they have released it yet. It's a full 8" lift that replaces pretty much all of your suspension components (read: very expensive).
No one else wants to even mess with the new Expy because of the IRS.
