I am getting ready to put in my LC coils and I know YES, I can use the factory FJ80 shocks with the coils. However, I also have Procomp ES3000's (made for the 4inch lift). My search has not yielded an answer to this question- Which shock would be better suited for the LC coils on a 4runner? I have heard a stiffer shock is better for the LC coils.

 

Kind of a six of one, half dozen of the other. I'd sooner use the LC shocks as they're probably a higher quality piece based on the application they're built for (FJ80's are a premium/flagship for Toyota). ES3000's are no better than any other cheap shock you can pick up from an auto parts store.
