Heavy Duty Rear Hatch Lift Struts?

[EddieC]

Do you mind sharing oem GM replacement part numbers please ? I have bought a pair of ACDELCO 5101245 Professional and they fail in winter.
Previously tried Stabilus SG330076 and SG330077 pair and the same result: work great until freezing temperature.

Just saw this. Better not tell you because they don't live up to the originals in the second winter. Bumping my head on the door.
