Chrysler says that the install ( 2 in lift ) should take 2.2 hours. That information is directly on the Parts desk computer at the dealership. I think the going rate is about $125 per hour labor. My parts guy said they used to get 4 hours. Said he needs at least 3 hours pay for the labor. Even 3 hours is $375. Tires maybe 1.5 hours on the long end? Thats 4.5 hours for $562.50. Seems like a lot for labor to me. But thats what it costs!
