New 10R1055 Caterpillar C12 Garrett GTA4294BS Turbocharger - Turbo Centre Production Line

The 10R1055 Turbocharger is a purpose-matched Garrett GTA4294BS assembly for Caterpillar C12 12.0L, Heavy-duty highway, vocational, and industrial C12 applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 10R1055, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The Garrett GTA4294BS is a pneumatic-wastegated turbo engineered for the Caterpillar C12. It combines a large-frame compressor with a matched turbine and wastegate assembly so the engine can build usable boost at lower speed while limiting drive pressure at higher load. This balance is critical on C12 highway and vocational engines, where sustained pulling power, stable exhaust temperature, and reliable oil sealing matter more than peak boost alone.

This listing is supplied as the turbocharger configuration shown. Correct installation requires clean oil feed and drain paths, a sealed charge-air and exhaust system, proper air filtration, and confirmation that the original failure did not leave debris or contamination in the engine system.

Turbo Centre Production Line units are assembled from new components to controlled specifications. The rotating group is balanced, bearing clearances and oil passages are checked, housings and control hardware are inspected, and wastegate or vane operation is verified where applicable before shipment. The result is a direct-replacement turbo built for dependable highway, vocational, fleet, and industrial service without a core return requirement.
