Hi Maraguez,

The Air Lift spring insert for the Sportage is really too short even for the stock springs. The one for the Nissan Pathfinder is about 2" longer and much better for either stock Sportage springs or the Eibachs. In fact, they would probably prevent the Eibachs from saging.

Yes, airsprings are TOO progressive if the air pressure is too high but if you limit your lift to less than 1" it is fine. I really use mine to keep the stock empty rear ride height with a load.
