Used Mercedes-Benz GLC Bonnet Strut

Yes, the GLC uses gas-filled bonnet struts (also called bonnet stay struts or bonnet lift struts) to prop the bonnet open - these are the standard mechanism on this model rather than a manual stay rod. There are typically two struts, one on each side of the engine bay. If yours have failed and the bonnet no longer stays up on its own, replacing the struts is a straightforward fix.

The GLC has had two main generations: the first-generation X253, produced from 2015 to 2022, and the second-generation X254, which launched in late 2022 onwards. The two generations have completely different front-end structures, so bonnet struts from an X253 will not fit an X254 and vice versa. Always match parts to your generation, which your registration will confirm.

Both a 2018 and a 2021 GLC fall within the first-generation X253 (2015-2022), so they share the same basic platform and front-end structure. The X253 received a facelift around 2019, which updated the lights and grille, but bonnet struts are a mechanical fitting in the engine bay rather than a visible panel, making a cross-facelift swap more likely to be straightforward than with trim panels - however, confirm the part number against your registration with the breaker before buying to be certain.

The X253 GLC was facelifted in 2019, updating the exterior styling, but bonnet struts are functional components mounted inside the engine bay and are generally unaffected by facelift styling changes. That said, it is always worth quoting your exact registration to the breaker so they can verify the part number matches your specific build, as minor specification changes can occur across a production run.

Trim level does not affect bonnet strut fitment - whether your GLC is SE, Sport, AMG Line, or any other trim, the bonnet and its struts are the same across the range within a given generation. Trim differences on the GLC relate to interior specification, alloy wheel style, and exterior detailing rather than the bonnet mechanism. You can safely buy from any equivalent-generation GLC regardless of trim.

The GLC Coupe (C253) and the standard GLC SUV (X253) share the same generation platform and were produced over the same period, but they have different body structures and bonnets, so the struts may not be interchangeable. Confirm with the breaker by providing your full registration, as they can check the part numbers from both vehicles to see whether they match before you commit to buying.
