Liftless 2 inch lift

Check the thickness of the spring metal the rear should be thicker.

I'm almost certain I haven't. Mainly because the dampers are front and rear specific and the rear dampers were packaged within the rear springs and the front ones packaged within the front springs. Also, the front springs were driver/passenger side specific. I do believe the rears were thicker too as Wickford90 said.
It would make sense that the fronts were incorrect as they were the same length as the ones I took out, whereas the rears were a good inch or two taller. I just assumed the extra height would come from added spring stiffness as mentioned before.
