Just to let you all know, if you're interested, a guy is selling a 6" Skyjacker lift w/ 36" Parnelli Jones tires on 16" Mickey Thompson wheels on EBAY. If you go to EBAY, just type Superduty in the search box. Here is what his description is:

"This is a nice Skyjacker 6" Lift Kit for a '99-01 Ford Superduty Truck or Exscursion. It is all Spring, no lift blocks. Has 4 Skyjacker shocks. Also comes with 36x14.50x16 Parnelli Jones Dirt Grip tires mounted on brand new Mickey Thompson Classic 2 Wheels. Even has brand new Lug Nuts. The wheels have never even been mounted on a vehicle. Two of the tires are brand new and two are 99% new. This is a complete lift with Pitman arm and brackets to correct the steering geometry. My loss is your gain. This must be picked up, I WILL NOT SHIP!! I can met you within 150 miles of Farmington, New Mexico. I can get pictures if you like. Please email with any questions. THIS WOULD COST OVER $3000 EVEN THROUGH THE WHOLESALERS IN THE OFFROAD MAGAZINES!!!!!"
