Mercedes-Benz CLA Anti Roll Bar Replacement Parts

The CLA has two main generations: the C117 (2013–2019, with a facelift around 2016) and the C118 (2019–present). The anti roll bar exists on both generations at both front and rear axles, but the two generations use completely different platform geometry and the bars are not interchangeable between them. Stick within the same generation when sourcing a used bar, and confirm the exact part with the breaker against your registration.

Both a 2015 and a 2017 CLA fall within the first-generation C117 (2013–2019), so they share the same basic platform and the facelift was a visual and trim update rather than a suspension architecture change. That said, whether the anti roll bar is identical either side of the 2016 facelift is something you should confirm with the breaker against your registration, as minor running-gear revisions can occur mid-generation without changing the model name. Don't assume fitment without that check.

Engine size can influence anti roll bar diameter or stiffness because heavier or more powerful variants are sometimes given uprated suspension components to suit their weight and output. A CLA 200 and a CLA 250 or AMG-line variant may not share identical bars, so it is worth telling the breaker your exact engine code and power output as well as the registration. Never assume a bar from a lower-powered CLA will be a direct swap onto a higher-powered one.

Trim level alone — SE, Sport, AMG Line — does not in itself change the anti roll bar, but AMG Line models in the CLA range were often paired with lowered or firmer suspension packages that could include different bar specifications. Because sport suspension differences are not something we can state as fact here, confirm with the breaker that the bar from their donor car matches your exact suspension setup using your registration. Cosmetic trim differences between the cars are irrelevant to fitment.

Yes — the front and rear anti roll bars are entirely different parts in size and design, so always tell the breaker which end you need. On the CLA, both axles are fitted with anti roll bars, so there is no question of one end not having one. Getting this wrong is an easy mistake when ordering, so double-check your order confirmation before the part is dispatched.

No — the C118 (2019–present) is built on a different platform to the C117 (2013–2019) and the suspension geometry, mounting points and bar dimensions are not compatible. Always source a bar from the same generation as your own car, and give the breaker your registration to confirm the exact specification. Mixing parts across the generation boundary risks the bar either not fitting at all or not performing correctly.
