Mercedes-Benz G-Class Wheel Arch Liner Replacement Parts

The G-Class is unusual in that it retained the same fundamental W463 body shell from 1989 right through to 2018, when the fully redesigned second-generation W463A arrived. Liners from within the original W463 generation (1989–2018) are far more likely to interchange than anything crossing into the W463A (2018-onwards), which has a substantially different body. Confirm the exact pressing year and door position with the breaker against your registration before buying, as mid-generation panel updates can affect liner shape.

Almost certainly not without modification — the 2017 car is the original W463 generation, while the 2020 is the redesigned W463A that launched in 2018 with a completely different body structure despite keeping the same boxy silhouette. These two generations should be treated as entirely separate vehicles for body panel and liner fitment. Always confirm with the breaker against both registrations before purchasing.

Trim level does not affect wheel arch liner fitment on the G-Class — the underlying body shape is the same across variants including the G350d, G500, and G63 AMG within the same generation. You may find that some AMG or aftermarket wide-body kits use different arch assemblies, so if your car has flared or extended arches, flag this to the breaker as it can affect liner choice. Stick to matching generation (W463 or W463A) and you should be fine otherwise.

Yes — NS (nearside, passenger side) and OS (offside, driver side) liners are handed and are not interchangeable with each other, so always specify which side you need when contacting a breaker. The G-Class is only produced as a five-door body style, so door count is not a complicating factor here. Make sure you also confirm front or rear arch liner, as these are different parts too.

Yes, wheel arch liners are a genuine fitment on the Mercedes-Benz G-Class — they are plastic inner liners fitted behind the wheel arches to protect the body from road debris and moisture, and they are present on both the W463 (1989–2018) and W463A (2018–present) generations. They are sometimes missing or damaged on older examples due to off-road use or age, so good used ones are a practical find from a breaker. Make sure to specify front or rear, NS or OS, and your generation when requesting a quote.

Both the 2005 and 2015 cars fall within the long-running original W463 generation (1989–2018), which retained broadly consistent bodywork throughout its life, so there is a reasonable chance of compatibility. However, Mercedes did make incremental panel and component changes across those decades, so fitment across a ten-year gap is not guaranteed. Confirm with the breaker against both registrations, specifying front or rear and NS or OS, before committing to the part.
