Welp, here goes my first post! I just bought a 2004 Tahoe Z71 with 150,000 miles. It has aftermarket leveling keys on it. I have adjusted them two different times for about four total turns on each torsion key bolt. Every time I lower the Tahoe it sits about an inch higher and then after driving it settles back to its original ride height. My front sits about 3/4 of an inch lower than the rear. I’m afraid I’m running out of bolt on the keys and don’t want to go much higher. Any ideas?
