504158937 upper mirror arm cover – compatible with IVECO STRALIS

504158937 upper mirror arm cover is a protective trim cover designed to shield the upper mirror arm area from airflow turbulence, road spray, and daily abrasion in fleet service. This listing is for the left-hand side, and it is identified by OE reference 504158937 to help match the correct mounting profile before ordering.

On long-haul and mixed-route trucks, the mirror arm area is constantly exposed to vibration, pressure changes at highway speed, and frequent wash cycles. The 504158937 upper mirror arm cover helps protect the arm section and nearby fasteners from direct impact and grime buildup, supporting a cleaner fit and reducing the chance of cover edges loosening over time. When the cover is seated correctly, it can also help reduce rattling caused by wind buffeting around the mirror arm.

Common replacement triggers include cracked plastic after minor depot contact, missing trim after repeated vibration, or worn clip points that no longer hold a tight fit. Replacing the 504158937 upper mirror arm cover can restore a tidy mirror-arm appearance and protect the mirror arm interface during daily lane changes, reversing, docking, and yard maneuvering where mirror stability matters most.

Typical applications for the 504158937 upper mirror arm cover include models used across regional distribution and construction logistics. Application examples (verify mounting configuration on the vehicle): compatible with IVECO Astra HD9 (2018), compatible with IVECO Eurofire (2000/2008/2015), compatible with IVECO Trakker (2004/2007/2013), compatible with IVECO Stralis (2002/2013/2016), compatible with IVECO Eurocargo II (2003), compatible with IVECO Eurocargo III (2008), compatible with IVECO Eurocargo IV (2015), compatible with IVECO X-WAY (2021).

For fleet workshops and distributors, stocking the 504158937 upper mirror arm cover supports fast cosmetic repairs and preventive trim replacement during mirror inspections. Use the OE reference on bin labels to reduce picking errors across similar mirror-arm cover variants.

5. Install the 504158937 upper mirror arm cover evenly, confirming full engagement on all retention points.
6. Final check: verify the cover is secure and does not rattle through the mirror adjustment range.
