Mercedes-Benz GLA Side Skirt Replacement Parts

The GLA has two generations: the first-generation X156, built from 2013 to 2019, and the second-generation H247, which launched in 2020 and is still in production. Side skirts are generation-specific, so a skirt from an X156 will not fit an H247 and vice versa. Always confirm your generation before sourcing a used part from a breaker.

Both a 2015 and a 2017 GLA fall within the first-generation X156 (2013–2019), and the X156 received a facelift in 2017 that brought styling updates including revised bumpers and trim details. Because the facelift boundary sits within this window, you should confirm with the breaker whether the specific skirt from a pre-facelift car matches your post-facelift car, or vice versa, as the styling profile may differ. Never assume a fit without checking against your registration.

The X156 facelift arrived in 2017 and brought exterior styling changes that may affect how side skirts align with the front and rear bumpers they meet. Whether the pre- and post-facelift skirts interchange is something you should confirm directly with the breaker against your registration, as the answer can depend on the exact panels already fitted to your car. Name the facelift year (2017) when you contact the breaker so they can cross-reference the right part.

Trim level does not affect the structural fitment of a side skirt to the body, but the GLA's AMG Line trim uses a distinctly styled skirt that differs visually from those on Sport or SE variants. If you source an AMG Line skirt for a non-AMG Line car it will bolt to the same fixing points, but the aesthetic will not match your front and rear bumpers unless those are also AMG Line. Confirm the trim the donor skirt came from with the breaker so you know exactly what you are getting.

Used side skirts from a breaker will almost always come in the donor car's original colour, and bare plastic skirts can be professionally resprayed to match your car's paint code. The colour of the donor part does not affect fitment, so don't let a colour mismatch put you off an otherwise correct skirt. Factor in respraying costs when comparing prices from different breakers.

No — engine choice and drivetrain layout (whether your GLA is front-wheel drive or 4MATIC four-wheel drive) have no bearing on which side skirt fits your car. The correct skirt is determined by generation (X156 or H247) and whether your car is pre- or post-facelift. Confirm the generation and facelift status with the breaker and you can disregard drivetrain entirely.
