Im pretty sure you would need it. I have that lift and with a 1" MML I have no vibes. I think you could do a MML w/o a BL if you relocate the fan shroud, dont quote me on that though.
If you are ok w/ a tcase drop, you can make your own with some longer bolts and a few washers. Add one or two, drive it. Still have vibes? Add another washer or two. Repeat until no vibes. If drop it more than about an inch and still have vibes, theres more to it than the lift.
