Used Mercedes-Benz SLK Anti Roll Bar

Yes, the SLK has anti roll bars at both the front and rear axles across all generations — it is a sports roadster with double-wishbone or multi-link suspension depending on the generation, and anti roll bars are a standard part of that setup. So if yours is worn, cracked, or the drop links are gone, a replacement bar from a breaker is a legitimate search.

The SLK ran across three generations: the R170 (1996–2004), the R171 (2004–2011), and the R172 (2011–2016, when the model became the SLC). Generation matters significantly for anti roll bar fitment — the suspension geometry, bar diameter, and mounting points differ between R170, R171, and R172, so you must match the generation of the donor car to your own.

A 2003 car is an R170 and a 2005 car is an R171, which means they sit either side of the 2004 generation change — these are different platforms with different suspension designs, so the bars are not interchangeable. Always confirm the R-designation of the donor car with the breaker against your registration before purchasing.

Engine size can influence anti roll bar specification on the SLK, as Mercedes fitted different suspension tuning across the range — the AMG variants (such as the SLK 55 AMG) in particular may carry uprated bars compared to the four-cylinder models. Confirm with the breaker whether the donor car's engine matches yours, especially if you are buying from or for an AMG or high-output variant.

The trim designation in this case refers to the engine variant rather than a cosmetic trim level, and engine size can affect suspension specification, so it is worth mentioning your exact variant to the breaker. Purely cosmetic differences between cars — colour, interior spec — have no bearing on anti roll bar fitment whatsoever.

Yes, absolutely — the front and rear anti roll bars are completely different parts with different dimensions and mounting arrangements, so you must tell the breaker which end you need. It is also worth confirming whether you need the bar itself, the drop links, or the complete assembly including bushes, as breakers may list these separately.
