This HX55 core is listed for Cummins M11, ISM11, and ISME engine applications, including Freightliner, International, and Alexander Dennis vehicles. Use the 65+ associated OEM reference numbers, such as 3580726 and 4027878, to help confirm fitment. Verify your specific turbo model, engine code, and vehicle application before ordering. This is an aftermarket replacement application; always cross-check part number FOR 3800471 against your existing unit to ensure correct configuration.

Technical Notes

The HX55 core assembly features a central shaft with threaded fasteners, connecting the compressor and turbine wheels within a cylindrical bearing housing. Visible machined flange surfaces and radial support ribs on the turbine housing indicate standard heavy-duty construction. Buyers should verify the specific turbo configuration, including mounting orientation and port alignment, against their existing unit. For fleet or mixed-vehicle applications, confirm the engine code (M11, ISM11, or ISME) matches the application path. Use representative OEM references like 3580726 or 4027878 to cross-check part numbers before finalizing orders.
