The lifter failures reported with the 5.3 with DFM seem to have been fairly widespread and documented, My understanding is that GM has been replacing the failed lifters with an updated lifter.
Seems to me, at some point the updated lifters should have been incorporated in the manufacturing / assembly process. If this true does anyone have an idea when the new lifters started being used in the 5.3?

All new trucks have the updated lifters

Parts Man1 – Thanks for the response. Would that include the 2022 RST build date 5/26/22 which I have been waiting on for the past 10 months?
