Fitment comes from dealer cross-references, not a Holset catalogue page. ISF2.8 / ISF3.8 HE221W turbos use different numbers (e.g. 3774227) — match the Assy and Cust numbers on your existing turbo's plate. Fitment and interchange data is compiled from manufacturer catalogues and cross-reference listings and can change at engine serial-number breaks. Quote your engine serial number and existing part number when you call and we will confirm before dispatch.

Genuine Holset HE221W wastegated turbocharger, assembly 4044885 with Cummins customer number 4044888, serial T2503126126 — the Holset plate reads Assy 4044885 / Cust 4044888 / Model HE221W, and the turbine housing is cast 4031562 (see photos).
