Whoa... Just for the record and archives....
Rubicon comes with Jeep factory air lockers and 4.10/4.11 gears in front and rear Dana 44 axles. It also has a 4:1 low ratio transfer case, 16" aluminim wheels, and 1" wider fender flares.
A sport will have a front Dana 30, rear will be a dana 35 or optional dana 44. Gears, depending on year, engine, and transmission (do searches or read the FAQ) - can be 4.11, 3.73, or 3.07. A factory rear limited slip is also an option.
All jeep wranglers have a 2.72:1 transfer case, except the rubicon.....
