Mercedes-Benz GLS Anti Roll Bar Replacement Parts

The GLS has two main generations: the first-generation X166, produced from 2016 to 2019, and the second-generation X167, which launched in 2020 and is still current. The anti-roll bar design differs between these two generations, so it is essential to match the part to your generation rather than just the model name. Always confirm your generation with your registration before ordering from a breaker.

This crosses the boundary between the first-generation X166 (2016–2019) and the second-generation X167 (2020 onwards), and these are fundamentally different platforms, so the anti-roll bars are very unlikely to interchange. You should treat these as non-compatible and source a bar from the correct generation. Confirm the part number with the breaker against your exact registration to be certain.

The GLS is a large, heavy SUV and was offered with a range of engines including six-cylinder and eight-cylinder units, and the heavier or more powerful variants can use a stiffer or differently rated anti-roll bar setup to suit their weight. Because of this, it is worth telling the breaker your exact engine size or variant when requesting a quote, rather than just the model name. The breaker should check the part against your registration to confirm the correct specification.

Trim level alone — for example AMG Line versus standard specification — does not fundamentally change the anti-roll bar in the way that engine size or generation does, and in most cases the running gear is shared across trim grades. However, if your car has AMG suspension or an optional air suspension setup, the anti-roll bar configuration may differ, so confirm with the breaker whether your car carries any suspension package upgrades. The breaker will be able to verify the correct part against your registration.

Yes, the GLS has separate front and rear anti-roll bars and they are not interchangeable with each other, so you need to be clear with the breaker about whether you need the NS/OS front bar or the rear bar. The front and rear units are different in diameter and mounting design, and mixing them up would result in the wrong part. Always specify front or rear clearly when requesting a quote.

The GLS is widely fitted with air suspension, but air suspension does not eliminate the need for anti-roll bars — the GLS retains conventional anti-roll bars at both the front and rear axles to control body roll independently of the air springs. So the part genuinely exists on the GLS across both the X166 and X167 generations. If your car has the standard steel spring suspension rather than air suspension, the anti-roll bar is also present, so this is a valid part to source from a breaker regardless of your suspension type.
