Used Mercedes-Benz GLS Shock Absorber

The Mercedes-Benz GLS first generation (X166) ran from 2016 to 2019, while the second generation (X167) started from 2020, so these are different generations with different platform and suspension geometry. Shock absorbers from the X166 will not cross to an X167. Always confirm with the breaker against your exact registration to be certain which generation your vehicle is.

Both 2017 and 2019 GLS models fall within the first generation X166 (2016–2019), so you are within the same generation and fitment is much more likely. That said, you should still confirm with the breaker against your registration, as variants with air suspension or sport suspension tuning may differ. Never assume fitment without checking.

Yes, engine size can influence shock absorber specification on the GLS because heavier, more powerful variants may be set up with different damper rates to suit their weight and power output. When contacting a breaker, give them your exact engine size alongside your registration so they can match the correct unit. Running gear tends to vary with weight and power more than with bodywork or trim level.

Trim level alone does not determine shock absorber fitment on the GLS — AMG Line is primarily a cosmetic and styling package rather than a fundamentally different suspension specification in most cases. However, whether your car was optioned with air suspension or a specific sport damper package is a separate question that trim name alone does not confirm. Confirm with the breaker against your registration to ensure the damper rate and fitment matches your actual setup, as these variants do exist on the GLS.

Yes, always specify NS (nearside, passenger side) or OS (offside, driver side) when ordering, as left and right shock absorbers are handed and will not swap across sides. This is especially important when sourcing a used unit from a breaker, as mislabelled parts do occasionally turn up. Double-check the side with the breaker before they pull the part.

The 350d and 500 are different engine sizes within the GLS range, and because larger, heavier engines can result in different suspension tuning and damper specifications, these may not be a straightforward swap. Both engines were available in the same X166 generation (2016–2019), so the generation boundary is not the issue here, but the weight and power difference may matter. Confirm with the breaker against both registrations before proceeding.
