NLOVNIT is correct. 4x4, qaudra-tracII or qaudra-drive. You will need a base plate and wire for lights. A supplemental brake system is really a must considering it wieghs nearly 5K.
I just did the base plate install on mine a few weeks ago, there is a thread here about it. Now if I'll get off my lazy behind and install the brake and light wiring it'll be ready.
