What was wrong with the Alcan springs? I would think that 63" springs with 3" blocks was a step in the wrong direction that could lead to serious axle wrap? Also, I thought that Chevy springs required a load to really flex well possibly making them better suited for a 4runner application. I am no expert, but not many people dump Alcan springs.
What are you planning to do with the front Alcan springs? How much lift and how were they designed?
