The ACDelco brand isn't all OEM GM parts. They have expending into just another aftermarket reboxing brand (think a lower quality Beck/Arnley) that is widely available; up until now, the actual original OEM GM parts have not been available in regular or online parts stores.
Look up any GM car (even captive imports like the Pontiac Vibe will work). Rock lists two different parts under the ACDelco brand: their professional series (the aftermarket reboxing), and the GM Original Equipment. Even more interesting is with the Vibe (a rebadged Matrix): the professional series is listed as fitting both the Vibe and Matrix, while the GM Original Equipment part is listed as only fitting the Vibe.
For some parts, there are even separate GM OE parts for the base and GT Models (Vibe GT = Matrix XRS), whereas there is only one ACDelco Professional part for both models.
Who makes the ACDelco Professional shocks/struts? I know the OE dampers are KYB.
