x2. You will have to build your own lift.

I once examined this possability for my 3rd gen... OME coils and bilstein shocks for the added height of the spacers. I came to two conclusions.

1. I did not need that much lift for what I do.

2. I would require a diff drop to keep from blowing up CVs regularly.

I chose to go with the straight coils. I am very happy. I installed the diff drop and my CV angles are near horizontal.

My advice would be to do the OME lift with the 1" BL, as xskydivingdudex suggested. You will have more room for bigger tires, and less strain on your drivetrain. In a 4Runner, it is not your breakover angles that you have to worry about as much as your clearance.
