Compressor-cover labels: Customer P. No. 3537817, TURBO Serial No. D2603016086. Holset sticker: Data D2603016086, Serial 3537817, Model HX55W CHRA. Centre housing is cast HOLSET 4038899.

This is a CHRA / cartridge (compressor wheel, turbine wheel, centre housing). It is not a complete turbo with compressor and turbine housings. Oil ports are visible on the centre housing as photographed.
Public aftermarket pages title 3537817 as Holset HX35 / HX35W for Cummins 6BT. This unit’s Holset sticker says HX55W CHRA. We do not overwrite the plate with those catalogues, and we do not copy Dodge 6BT / Komatsu lists as fitment.
Not this product: Holset 5554144 HE300WG, Garrett 800854-5023S, BorgWarner 5326-101-3091.
Verified: a Holset-labelled CHRA, customer number 3537817, sticker model HX55W CHRA, serial D2603016086. Engine, vehicle, and complete turbo assembly number are not on these frames except the marks listed above.
HX55W catalogues elsewhere use other CHRA numbers (for example 3580726 / 4027878 on third-party pages). Those are not treated as equivalent to this cartridge.
