Used Mercedes-Benz CLA Rear Cross Member

The CLA runs across two clear generations: the first-generation C117 ran from 2013 to 2019 (with a facelift in 2016), and the second-generation C118 launched in 2019 onwards. The rear cross member is platform-specific, so a C117 part will not cross over to a C118 and vice versa – always tell your breaker which generation yours is before ordering.

Both the pre-facelift and post-facelift C117 CLAs share the same underlying platform, so the rear cross member can be compatible across the 2016 facelift boundary – however, whether the pressing is identical is something you should confirm with the breaker against your registration, as minor structural changes can occur mid-generation without being widely publicised. Give your breaker your full reg so they can cross-reference the part from their donor car. Never assume fitment without that check.

Yes, body style is the first question to get right here – the CLA Saloon (four-door) and the CLA Shooting Brake (estate) have different rear body structures, and the rear cross member is part of that structure, so the two are not interchangeable. Always specify your exact body style to the breaker alongside your generation, as quoting the wrong one is one of the most common fitment mistakes on rear-end parts.

Trim level – whether that is SE, Sport, AMG Line, or any other – does not affect which rear cross member you need, as this is a structural chassis component that is the same across trims on the same generation and body style. You may find that trim-specific rear bumper valances or tow-bar preparation differ cosmetically, but the cross member itself is unaffected, so do not pay extra or restrict your search based on trim.

The second-generation CLA (C118) launched in 2019, so a 2019 and a 2020 car are both within the same generation and the rear cross member should be compatible in principle. That said, confirm with the breaker using your full registration to rule out any very early production differences, which can occasionally affect structural parts in the first model year of a new generation.

Give the breaker your full registration number, your body style (saloon or shooting brake), and confirm whether your car is a C117 (2013–2019) or C118 (2019-on) – these three details are the most critical for this part. Engine and trim level are not relevant to fitment here, so do not worry about stating those unless asked. A good breaker will cross-reference the part number from their donor vehicle against your reg before quoting, which is the safest way to proceed.
