Second Hand Mercedes-Benz B-Class Anti Roll Bar

The Mercedes-Benz B-Class W246 generation ran from 2011 to 2018, with a facelift in 2014, so a 2012 and a 2016 car share the same generation — but the facelift sits between those two years and can bring running-gear revisions. Parts from within the same pre- or post-facelift group are more likely to interchange, but crossing the 2014 facelift boundary means you should confirm fitment with the breaker against your exact registration before buying.

Yes, the B-Class is fitted with anti-roll bars (also called stabiliser bars) at both the front and rear axles across all generations, including the W245 (2005–2011) and W246 (2011–2018). The B-Class uses a front-wheel-drive-based platform, and anti-roll bars are a standard part of its suspension setup on both axles. When searching for a used part, make sure you specify whether you need the front or rear bar, as they are different components.

Trim level alone does not determine anti-roll bar fitment on the B-Class — the SE, Sport, and AMG Line trims all use the same basic suspension architecture. That said, if your car was ordered with an optional sport suspension package or lowered suspension, the bar dimensions or mounts could differ from a standard car, so confirm with the breaker against your registration if you are unsure whether your car has non-standard suspension.

The W245 (2005–2011) and W246 (2011–2018) are distinct generations with different platform dimensions, so their anti-roll bars are not the same and will not interchange. Always source a bar from the correct generation — tell the breaker your exact registration so they can match it to the right car.

For the B-Class, engine size is not typically a primary factor in anti-roll bar selection in the way it might be for brakes, as the running gear is broadly consistent across the petrol and diesel engine variants within each generation. However, if your car has the 4MATIC all-wheel-drive system fitted to some later W246 models, the rear suspension layout differs, so confirm with the breaker whether the bar you are looking at came from a 4MATIC or two-wheel-drive donor car.

Both a 2013 and a 2015 B-Class fall within the W246 generation (2011–2018), but the 2014 facelift sits between them and can involve suspension component changes. Parts from within the same pre- or post-facelift sub-group are a closer match, so crossing that 2014 boundary — as this question does — means you should give the breaker both registrations and let them verify the part numbers match before you commit.
