SDA or SDM suspension, how to tell?
I did a search, all I came up with is a thread on build sheets about the SDA or SDM sales code which represents what suspension a Commander was built with (2010).
Apparently SDA means a Standard Duty Suspension.
So what does SDM mean?
Well, other than asking for a build sheet for my Commander, which I may have to do.
I remember some discussion about the Factory Tow Package upgrading the rear suspension, would that be the SDM sales code for Commanders?
I ask because, I'm considering new struts/shocks, the OEM parts catalogue shows only one front strut part number, but two rear shock part numbers, one for "SDA" sales code and the other for "SDM".
I have a 2010 Commander without the factory Tow Package, 3.7L V6, NAG1 Trans and QT1 drivetrain. So its a good guess its SDA, but I'd like to know for sure, especially since I don't know what SDM is, it might be a softer shock than SDA.
