I just saw an add for the Rancho quick lift system and wanted to know if they make one for my 07 z71 tahoe, i already have a 2inch leveling kit and wanted to know if i could add the strut with the leveling kit to get more lift? has anyone tried this? Also im running 285/65 nitto terra grapplers on the stock 18s and feel like the truck isnt looking as beastly as i thought and figured an extra 2inchs of lift could fix that with some bigger tires. If this cant be done my other question is does the Rancho 4inch lift perform well off road and on road?
