Here is what I have found, if it's factory hard top Jeep you will get about 4 inches of lift, soft top about 3 inches. Even though the TJ and the Sportage weigh about the same the Jeep is heavier in the rear, on my Jeep the springs are compressed about 1 1/2" more than on the Sportage. My Sportage springs came off a hard top and my Jeep is a hard top.

Hope that helps a little, Dennis
