body lift/suspension lift

hey guys...any answers/help would be greatly appreciated.

I have a 2000 Sport Package 4-runner(hood scoop)
I'm gonna get a 3 inch body lift soon.
There's no available suspension kit right now for the 2000 runner...
What I want to know is....do I need to get the suspension lift also? Would it help for offroading?
Or the body lift is enough since the 4-runner already has good clearance?
Thanks!
