Rubicon's also have the D44 axles front and rear. On other models, the Sahara and X, the rear is still D44 but the front is a D30. The D30 is fine for the street and stock tires but once pushed off-road they'll show you why it's important to always carry good hiking boots.
If you've got the money call up AEV and get er built, best of the best! If you're not into the off-road thing and just hitting the mid life deal...grab a Rubicon with a small lift and some 35's.
