Some do. 13 parts fit every engine; the other 14 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of drivetrain problems on a 2021 Alfa Romeo Stelvio?

What should I replace at the same time?
Where labor overlaps, replace the differential or transfer-case fluid with any axle or seal job while everything is already open.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 Alfa Romeo Stelvio was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2021 Alfa Romeo Stelvio?
First match the engine — each row shows which engine(s) the part fits. Then a torn CV boot caught early is a cheap boot kit; caught late it is a whole axle — inspect before deciding which to buy. The notes column carries position and trim qualifiers where they apply.
