Are the rear FJ springs load rated higher or just generally longer than stock 4runner springs? Thanks

From my understanding the FJ springs have a higher spring rating. I did the 5100/FJ swap (leaving the perch on the bottom setting) and netted exactly 1" of lift with my v6. I plan on moving the perch up one spot to the .85" setting in the near future however.
