This is the Garrett 848212-5003S, a new turbocharger, not a rebuild, for the GM 6.6L Duramax with RPO code LGH, which has L as the eighth digit of the VIN. The LGH is the Duramax used in 2011 to 2016 Chevrolet Express and GMC Savana vans, in late 2010 vans built with that engine, and in some Silverado and Sierra HD trucks, cab and chassis included. Catalogs list the turbo model as GT3582VA. It replaces GM 12640123 and 12642130 and Garrett 785580-0006 and 800563-0002. The Garrett remanufactured version of the same turbo is 848212-9003S.

The LGH turbo is not the LML pickup turbo. The two engines share the model years, but the turbos are different part numbers and do not interchange: the LML takes Garrett 848212-5002S. On a cab and chassis truck, read the number on the tag of your old turbo or check the RPO code before you order. Sticking vanes, low boost, oil in the intake and shaft play are the usual reasons these come off, so check the oil feed, the drain and the intake tract before the new one goes on.
