Can I lift a 15 w/ heavy duty tow package?

[dallasbbq]

I've read a few posts stating you cannot lift a 15 with auto leveling. My Yukon has the heavy duty tow package w/ premium smooth ride suspension with air leveler. This is a little different from the Denali which has the Magnetic Ride Control. I'm not sure which suspension is the problem. Heavy duty w/ air level or Magnetic Ride Control. Any input would be appreciated. My installer typically uses the Daystar kit.

you lifting or leveling the truck? Sounds to me like you are leveling. You should be fine regardless, but your installer would be able to be 100%.
