As far as I know - none of them did, as they all came equipped with the F55 Magnetic Ride suspension. And - you can't have both.
You should have a ride selector switch on the console - assuming you do, you have F55 and not Z51.
On your glove box door you will find the RPO sticker that lists all of the options that are on the car as equipped from the assembly plant. You should see FE1 which is the base suspension, as well as F55 which is the Magnetic shocks.
