Mercedes-Benz GLS Headrest Replacement Parts

The GLS has two main generations: the first generation (X166, 2016–2019) and the second generation (X167, 2020–present), with the X167 receiving a facelift around 2023. Headrests are interior trim parts and generally match within the same generation, but crossing from an X166 to an X167 is very unlikely to work due to differences in seat design and mounting points. If your vehicle sits close to the 2019–2020 changeover, confirm the exact generation with the breaker using your registration before buying.

Yes, trim level matters for the GLS because higher trims such as AMG Line and Maybach variants often feature different seat designs — including different headrest shapes, upholstery materials, and built-in features like rear-seat entertainment screens in headrests. A headrest from a base AMG Line seat will not necessarily match a Maybach or Executive rear seat. Always tell the breaker your trim level so they can match the correct seat style.

For front headrests, driver's NS (nearside, left) and passenger's OS (offside, right) headrests are usually identical within the same trim and generation, but rear headrests can vary in position and design, particularly on the third-row seats. It's worth specifying which row and which position — front, second row, or third row — when contacting a breaker. This helps avoid getting the wrong part, especially on Maybach versions where individual rear seats may have unique headrests.

This spans the X166 to X167 generation change, and fitment across that boundary is very unlikely — the seat mountings, headrest stalks, and overall seat designs differ between generations. You should source a headrest from within the correct generation for your car. Confirm the generation against your registration with the breaker to be certain.

Some GLS variants, particularly in higher trims, feature rear headrests with integrated entertainment screens or electrically adjustable mechanisms, and these will have additional wiring connectors that must be compatible with your vehicle's system. A plain headrest from a lower-trim vehicle will not replace a screen-equipped headrest without losing functionality, and vice versa. Confirm with the breaker exactly what type of headrest is fitted to the donor vehicle before purchasing.

No — engine choice (petrol, diesel, or hybrid) and drivetrain make no difference to headrest fitment on the GLS. Headrests are matched by generation (X166 or X167), trim level, and seating row position, not by what's under the bonnet. Focus your search on getting the generation and trim right rather than worrying about engine codes.
