What type of suspension do I have?

I recently purchased a used 2000 LT, with the 5.3. I have the towing package, but do not know how to find out what suspension I have. Is there a way to tell if I have the standard, Auto ride, or Premium ride suspension?

Call your local dealer and ask the service department what code numbers would be inside of the glove box for the different ride packages. Just match yours up to find out wich one you have.
