The OP's stem is shorter and could account for using a smaller Zipp label and graphics come in different versions over the years from what I've seen. It could also be an older version stem that doesn't look exactly the same at the steerer clamp or just distortion from the photos but maybe worth contacting SRAM about.

As far as I know it’s a legit stem. It came from a bike shop and came in normal Zipp packaging:
The stem on the website you linked to is showing the +/- 6° stem, so the angle is much less than the +/- 17° stem I ordered.
And the logos are slightly different due to its shorter length (80mm) than what’s usually shown on websites (100mm or more most likely.)
I ordered a cheap headset press that should arrive today and I’ll double check making sure the cups are in and straight. I will also try a different spacer though pretty sure it won’t matter because they all came in the same package.
Stay tuned?
