Nice ride you got there. My friends' have a Gx470 that we took all over Southern Utah and Colorado. Totally stock. You will need to be aware of your line and choose trails wisely. but you can go many places in stock form.
If you have the Air suspension lots of folks choose to replace them to avoid a rock taking them out on a trail. This can be done if you choose to get a lift.
The Gx470 if very similar to my 2006 4Runner, I went with OME BP51 and springs approraite for my typical load out. Let me know if you would like more details on the lift
Thank for the info
