Second Hand Mercedes-Benz GLS Suspension Leg

A suspension leg (also called a strut or MacPherson strut) is a combined spring and damper unit that forms part of the front suspension on many vehicles. The Mercedes-Benz GLS uses a different front suspension layout — a multi-link or double-wishbone arrangement with separate dampers and springs rather than a combined strut assembly — so a traditional suspension leg as a single bolt-on unit does not exist on this model. If you need front suspension components for your GLS, you are most likely looking for a separate front shock absorber, a coil spring, or a front suspension arm — a good breaker can help you identify the exact component you need.

Almost certainly, yes — the GLS does not use MacPherson struts, so sellers listing a 'suspension leg' for this model may be using the term loosely to describe a front shock absorber or damper. It is worth contacting the breaker directly and giving them your registration number so they can confirm exactly which component you need and whether their part matches your vehicle's suspension setup. The correct search terms for this model are more likely to be front shock absorber, front damper, or front suspension arm depending on which element has failed.

Quite possibly — if you have been told there is a suspension problem at the rear of your GLS, the part you need is a rear shock absorber or rear damper, not a suspension leg, as the GLS uses a multi-link rear suspension with separate components throughout. The GLS has been available across two main generations — the first-generation X166 (2012–2019) and the second-generation X167 (2019 onwards) — and these generations use different rear suspension components that are not interchangeable. Always give the breaker your full registration so they can confirm the correct part for your specific build.

Yes, for directional suspension components such as shock absorbers and suspension arms, nearside (NS, passenger side) and offside (OS, driver side) are not interchangeable, so you must specify the correct side when contacting a breaker. This applies equally to both the X166 first-generation GLS (2012–2019) and the second-generation X167 (2019 onwards), as both use sided front and rear suspension components. Always double-check the side before agreeing a purchase, as returning a used part can be difficult.

Trim level alone does not determine suspension fitment in the way that engine size or generation does, but AMG Line and AMG-badged variants of the GLS may have different damper or spring rates compared to standard specification vehicles. Whether a component from an AMG Line car fits a standard car of the same generation and engine is something you should confirm with the breaker against your registration rather than assume — differences in spring and damper rates mean a physically fitting part may not give the correct ride characteristics. The breaker can check build data against your reg to give you a confident answer.

This crosses the generational boundary between the first-generation X166 GLS (produced up to 2019) and the second-generation X167 GLS (from 2019 onwards), and the two generations use different suspension architectures, so components are not interchangeable between them. Within each generation, engine size can also influence suspension component specification, particularly on larger-engined variants, so this is worth checking with the breaker even when sourcing within the same generation. Give the breaker both registrations and they can confirm whether a specific part is a match.
