Second Hand Mercedes-Benz SLK Wishbone

The R171 generation covers 2004 to 2011, so both years sit within the same generation and wishbones are likely to be compatible, but you should confirm with the breaker against your registration as mid-generation running gear updates can affect fitment. Engine size can also play a role, so make sure the breaker knows whether you have the 1.8, 2.0, 3.0, or 3.5 litre variant. Never assume fitment without the breaker checking your specific reg.

The R170 ran from 1996 to 2004 and the R171 from 2004 to 2011, so these are different generations and the wishbones are unlikely to be a straight swap. Always route this cross-generation question to the breaker and give them both registration numbers so they can check the exact part numbers. Do not assume shared geometry between these two distinct platforms.

Engine size can influence suspension and running gear specification on the SLK, so it is worth matching the engine variant where possible rather than assuming all wishbones across the range are identical. Give the breaker your full registration so they can verify the correct part against your specific car. Trim level names like Kompressor or AMG Sport do not affect wishbone fitment on their own, but do confirm with the breaker if your car has any sport suspension package fitted.

Yes, NS (nearside, passenger side) and OS (offside, driver side) wishbones are handed and not interchangeable, so always specify which side you need when contacting a breaker. Make sure you identify the correct side on your own car before requesting a quote, as fitting the wrong side is a common and avoidable mistake. Your breaker will need to know the side along with your registration to supply the right part.

The R171 generation ended in 2011 and the R172 generation started from 2011, so a 2012 car is almost certainly R172 and a 2011 car could be either, making this a potential cross-generation boundary situation. You should confirm with the breaker using both registration numbers rather than assuming compatibility, as the platforms are different. The breaker will be able to check the exact part numbers to determine whether there is any crossover.

A 2016 SLK will be an R172, the generation that ran from 2011 onwards, and you should be looking for wishbones from other R172 donors rather than earlier R170 or R171 cars. Engine size matters within the R172 range, so let your breaker know your exact engine variant as well as your registration. Cross-generation fitment is not something a breaker can confirm without checking the specific part numbers against your car.
