I am going to assume a high lift jack would be the next best purchase before something bad like that were to happen, otherwise..............

 

I own a High Lift Jack and let me tell you, they are a great tool, especially to change a tire on a lifted truck, hell I've even used one as a winch. But I'd NEVER get under a vehicle held up by one! Those things are too damn skinny and unstable!!!

 

The engine can take it. the 37s will be fine.

 

I think you should ask the guy who has the 4.7L with 24 inch rockstars with muds. What ever happened to that guy? Maybe he can update us on his truck and how its holding up.

 

Bog city, too much unless you like workin on your truck every weekend.

But try it if you have the money who knows it might hold up for as long as you own the truck.
