Keep in mind it's not only the distance eye to eye but the height of the spring as well. If the heavier springs have more arch, the RV will sit higher. Also due to the fact that they have more capacity they will not squat as much under weight, again causing the RV to sit higher. The difference may be minimal, but something to consider since it will raise your center of gravity. Could also be a concern for someone who is vertically challenged, especially if you have a 3 step entrance. I'm not real familiar with the different Raptor models so don't know if it's a double or triple axle, but regardless, if you change one, change all.
