The number of leafs in a spring does not effect the ride height of the car. It does mean that the spring are more stable. If 6 leaf springs raise a car 2 inches, it's because the springs are arched at a level above stock. You can order 6 leaf springs from ESPO that deliver stock ride height or you can order them up to 2 inches above stock ride height in 1/2 inch increments.
