Can anyone tell me the correct Fram XG filter for a 2021 GMC Sierra 2500HD AT4 Crew Cab 4WD with a Durmax diesel? I get different numbers at different sites. Thanks Roger
 
That is not a XG. It is the wrong number, it is way to small and why are you asking about gas?
I posted an XG right before your post. I'm asking about gas to try & get you the correct diesel part number. Frams guide shows 6.6L and that's the same displacement as the 6.6L duramax... you see?

Best advice at this point is to take the AC delco part number I quoted & call fram.
 
I went to a GM parts web site and they showed the OEM part number as being 12684038. Their picture of the filter showed a AC Delco PF-26. The Fram page crossed the PF-26 to a Fram PH-2. That was all they showed. There were no XG references.

Fram shows that an ACDelco PF-26 crosses to a PH2. Fram shows an XG2 if you search for it on their website.

Fram Ultra XG2.

The last update to Fram's catalog is a failure. xreferencing and year/make/model engine..... toasted for too many vehicles.

XG has phased out the full synthetic media for a synthetic layer over cellulose layer. I wouldn't even bother with it, along with the state of flux that they're in..... move along and use another brand.

Glance at the Rockauto catalog for some PN's for your engine. There is an unreleased new Fram PN for your engine.

BTW, the Wix PN has a 400+ psi burst vs the 230psi for the Fram xg2/ph2/tg2 filters.

And, baldwin says: The B40150 features superior structural integrity to provide engine protection throughout the service interval.

Something tells me that I wouldn't want to use the cheaper gasser filter on that diesel engine.
 
Fram only shows the 6.8L V8 in their filter look-up pull down menu. 🤷‍♂️
