The 4x4 offroad package in 2002 is exactly like the fx4 package 2003+
the 2002 fx4 = the 2003+ fx4 level 2 package.
Unless it's an FX4 lvl 2 which has manual tcase/tranny and comes with bigger tires.
They dont come with bigger tires.. they come with bfgs and forged alcoa rims.
they arent all manual transfer case/transmission either.
