Being that your Trac is 2wd you can lift the frontend alittle higher then a 4wd Trac because you don't have to worry about the stress on the front CV Axle shaft (you don't have them), you will have to think about stress on the ball joints.
The do make 3" lift spindles for the Ford Ranger which will work on our trucks because the Explorer, Explorer Sport and the Sport Trac are all Ranger Based Vehicles which means they share mostly the same suspension and other parts.
The downside to doing the spindle lift is that you have to run the smaller Ranger brakes (with larger wheels and tires you won't have as much braking power). Right now with the 3" bodylift that you have on your Trac (they only make a 3" bodylift for our Trac's) you can clear the 265/75/16's with a little trimming on the cladding and wheelwells.
If all you want to do is level out your Trac then a simple Torsion Twist of 3" will give you the look that you want.
What are your plans for the truck? Just lifted look? Extra height, bigger tires for muddin' (not much in the way of trailin' in Florida, mostly muddin')?
There are alot of members from here down in Florida that would be more then hapy to help you work on your rig and go wheelin', hang out. I'm up in hell hole Pittsburgh (wish I still lived out west) or I would help you out in person.
Tellico is where I bought my lift shackles from but I would suggest you go with an Add a leaf setup (cheaper and easier to do and you can get this off ebay) OffTrac is the member that you would want to ask about part numbers and where he ordered his from.
As for the frontend you can crank your torsion bar bolts up (tighten them) to acheive the lift you want for the front (Zabteck Technologies) is where you can order longer torsion bar bolts if you need them, tell Todd Z that Jerry Gerner referred you. He runs mysporttrac.com and Zabteck.com. The only cost to lift the frontend this way is a frontend alignment and the cost of longer bolts if needed).
Hopefully this helps out some. It's alot easier then it sounds to lift these trucks until you get into doing Solid Axle Swaps like STrunner, Chad, TxPlates and some others have done and I'm in the process of starting once I get the rest of the parts I need or when I blow up the trans/ motor or rearend wheelin'.
