Product Description

The A1778851400  front bumper protector is a factory Mercedes-Benz part, specifically engineered for the AMG Line front bumper on the W177 A-Class (2019–2023 facelift). It is not compatible with standard (non-AMG) bumpers, which feature a different lower apron design

 The part installs neatly beneath the bumper fascia to prevent road marring and preserve factory styling.

Manufacturer notes: This piece is referred to as the “front bumper under tray” or “support at the bottom” and is explicitly marked not for AMG package on some parts diagrams, confirming its unique function difference across trim lines
