^^ Excellent Post. excellent info. Im on the sidelines for this one, but its info every lifted truck will need.

My question is, how do you know when its right? Is it some crazy geometric equation? Or is it right or wrong. Meaning, is the install fool proof?

Or do i need a shop to measure down to the millimeter and then do alignment afterwords?

I'd like to do this and install myself, but need it to be completely correct. Need the keep my passengers in good shape.
