Second Hand Mercedes-Benz GLS Bonnet Strut

Yes, the Mercedes-Benz GLS uses gas-filled bonnet struts to hold the bonnet open — these are a standard fitment across all variants of the model. Unlike older spring-hinged bonnets, the GLS bonnet relies entirely on these struts, so if yours has failed or weakened the bonnet will not stay up safely. All engine variants, including petrol, diesel, and AMG versions, share this setup.

The GLS nameplate covers two main generations sold in the UK: the first-generation GLS (X166), which ran from 2016 to 2019 and was essentially a renamed GL-Class, and the second-generation GLS (X167), which launched in 2020 and is still in production. Matching the correct generation is the most important step — struts from an X166 will not interchange with an X167. Always confirm which generation applies to your vehicle using your registration before ordering.

No — the 2016–2019 GLS (X166) and the 2020-on GLS (X167) are entirely different platforms with different bonnet assemblies, so the bonnet struts are not interchangeable between these two generations. This is a clear generational boundary, not just a facelift, so there is no grey area here. Make sure any used strut you source is confirmed to the same generation as your vehicle.

For the bonnet strut itself, trim level does not affect fitment — the bonnet panel and its struts are shared across standard, AMG Line, and AMG 63 variants within the same generation. You may notice cosmetic differences around the bonnet area between trims, such as different grille surrounds or badges, but the strut mounting points and the strut itself remain the same. A strut from any trim within your generation should be mechanically suitable, though we always recommend confirming with the breaker against your registration.

No — the bonnet strut fitment on the GLS is not affected by engine choice or drivetrain layout. Whether your GLS has a diesel, petrol, mild-hybrid, or AMG engine, the bonnet and its supporting struts are the same within a generation. Focus on getting the correct generation (X166 or X167) rather than worrying about engine variant.

Potentially yes for certain years, since the first-generation GLS (X166, 2016–2019) is the same platform as the late GL-Class (X166, 2012–2015), and these share significant front-end components including the bonnet. However, there may be differences between early and later X166 production that affect compatibility, so you should confirm with the breaker that the specific part number matches your registration before purchasing.
