My old '02 Edge had 2" lift blocks in the rear from the factory, If this is the case with yours, by removing the blocks in the rear (even if the original U-bolts will still work, I strongly recommend replacing them with new grade 8 U-bolts for safety reasons) and cranking down your t-bars to the point to get a height your happy with. You can lower it 2" for the price of an alignment and the new U-bolts (around $125+ tax CDN)
And trust me you will need a front end alignment, I put mine off for a couple months and chewed the front tires.
If you want to go any lower than that, I recommend going whole hog and do the control arms. My '97 Explorer is T-bars as well and I cranked them all the way down for a 3" drop. I had to cut 1" off my bump stops to get 1/2" of travel and my upper balljoints are at a very bad angle so I'm looking to do the control arm swap myself (not to mention I want 1" more out of the front anyway)
