Product Description
GTB1756VK 797001-0001 is the early RA428 Duramax 2.8L cartridge family used around Chevrolet S10 and Colorado commercial pickups.
External number alignment supports GTB1756VK rather than the broad catalog label GT22V, so the corrected model is used with a transparent matching note.
OE 12645143, oil-only cartridge configuration, and electronic actuator details should be confirmed before repeat supply.

GTB1756VK 797001-0001 helps repair networks support early Duramax pickups without mixing them with later 814067 turbo versions.
The corrected model reference improves search accuracy while retaining a nameplate requirement for market variants.
Distributor stock can be organized around 12645143 with clear early-year and oil-cooled notes.
Elecdurauto supplies the VGT core for aftermarket commercial repair programs.
GTB1756VK 797001-0001 uses variable-geometry control, and nearby commercial-vehicle versions can differ in actuator connector, calibration, vane mechanism, or housing orientation. Buyers should confirm turbo P/N 797001-0001 / 797001-5001S, OE 12645143, engine code, and nameplate photos before bulk release. Vehicle model and year alone are not sufficient for actuator-sensitive matching.
The turbo P/N should lead cartridge matching, while OE 12645143 connects the request to the commercial application. When suffixes differ, the removed turbo label and actuator details should decide whether the cartridge belongs to the same version. Related references can support research, but they should remain clearly separated from confirmed OE numbers.
A CHRA cartridge is suitable when the housings, VGT mechanism, actuator hardware, and mounting faces are reusable. The workshop should inspect vane sticking, wheel contact, cracks, and carbon buildup before installing GTB1756VK 797001-0001. When the actuator or geometry mechanism is damaged, a cartridge alone may not restore correct boost control.
Before installing GTB1756VK 797001-0001, the workshop should identify the earlier failure cause, clean the oil feed and drain paths, inspect intake contamination, and remove debris from the charge-air system. Oil and coolant passages must match the confirmed configuration. A correctly matched cartridge can still fail early when lubrication, cooling, housing contact, or foreign-object damage remains unresolved.
Returns are reduced when the order record contains turbo P/N, OE reference, engine code, actuator photo, nameplate photo, and commercial application. For GTB1756VK 797001-0001, warehouse teams should also separate market-year and power-rating variations. A number-led process is more reliable than matching only from vehicle descriptions submitted by repair customers.
GTB1756VK 797001-0001 can support distributor stock when demand is recorded by turbo P/N, OE reference, engine code, and commercial application. Elecdurauto recommends separating confirmed numbers from cross references and storing nameplate photos with repeat orders. Such records reduce picking errors, incorrect market-version substitutions, and after-sales disputes during mixed turbo core procurement.
