Does anyone have any or know where to find some good pictures of lifted Xterras?

Check out www.thenewx.org

There are tons of pictures of new X's lifted.

Here is mine with the AC Shackle Lift and 285/75R16 tires.

Very nice, I love the bumper.

where do you purchase the jack that is on your rack?

It's a HiLift jack. Available through most 4x4 parts companies. You can also get a similar jack called a "farm jack" through places like Harbor Freight or Tractor Supply Company.
