The great debate

I agree with Mod5V. I have built spring stacks for a couple of my rigs to get the ride height and stiffness I wanted. (60 Willys wagon, and 59 Suburban). You can actually do that without taking out your leaf springs... You will need longer center bolts in the springs and probably longer U bolts. Also, if you just want some lift, for cheap, you can use longer shackles in the rear, but that creates a different set of handling issues.
