It does raise it up a little when you fill them. I typically run 5 to 12 pounds, unless I am hauling something. 35 is the max, and 25 works well on a road course track or driving school, but it pounds your teeth on a bumpy road empty. 30 pounds made the Elky level with a load of flat patio bricks almost even with the top of the bed. 200# air shocks would have been on the bump stops, IF you could find a compressor anywhere that would fill them to that pressure. I have mine valved separately, because I read that if you have the right side tighter it helps you launch better. Although I doubt I will ever run a drag race. For me, I can keep an eye on the pressure and determine if one or the other is leaking. Only happened once, and it was the right side at the bag. I cut off the end and put it back on.... no leak. I would say they are more for load and handling. I would mess with springs for height.
