Looking at @NORCAL SS site, and the 00-920 kit says it works for both auto and non auto trucks.
I was always under the impression that the spring rates were different between the two because of the airbag on the rear shocks. Is it so minute that it doesn't matter?
I see some other kits are auto/non auto specific.
