My coach was loaded near the max ready for a three week trip. I suspect it was in the 17,700 lbs range. The front maxiums came just before we were to leave the next day so I moved the coach to the shop where I have lights. I measured the height on the left and right before I started and put my 4x4 blocks under the front jack pads and raised it up. I put the 6 ton jack stands under the front frame and let the jacks down. I followed the installations instructions and and set the coach back down on the tires. The difference in the height was 1.5". The SSF- 184-40-1 Sumo's operate in parallel to the leaf springs and thus add stiffness to the stock springs. I suspect if the front was lightly loaded the height gain would be much less. By-the way, we have put just over 14,000 miles on the coach since the installation. The spring's addition did not magically cure all the ride problems but it really helped with the lean and cornering of the coach. My wife thinks it rides better over the broken pavement, but I can't tell much difference except where the road is extremely rough.
