I thought 2" was close to max before the trailing arm hits the frame??
They were more of a extended spring perch than a block. Something Bill Turner Enterprises used to sell. Basically by making the "perch" taller the axle would ride higher into the notched frame before the trailing arm would hit the bottom of the frame. These were weld on in place of the original so you could correct the pinion angle.

I've attached a pic but the piece I'm talking about is sort of hiding.
One other trick is to flip the lower shock mount over and swap sides for a little extra room.
