Used Mercedes-Benz SLK Shock Absorber

Both years fall within the R171 generation (2004–2011), so there is a reasonable chance the shock absorbers are compatible, but the R171 received a facelift in 2008 and Mercedes occasionally revised suspension components around such updates. Name the exact year and engine size when speaking to the breaker, and ask them to confirm against your registration before you buy.

The R170 (1996–2004) and R171 (2004–2011) are distinct generations with different platform dimensions, so the shock absorbers are not a straightforward swap. Treat these as separate parts and source one from the correct generation; a good breaker will confirm this against your reg.

Yes, engine size can affect fitment because heavier or more powerful variants sometimes use different damper ratings to handle the extra weight and performance. Always tell the breaker your exact engine size — for example SLK200, SLK280 or SLK350 — so they can match the correct unit to your car.

Engine tune and output can influence suspension specification, so an AMG-badged SLK may carry different damper components compared with a standard Kompressor of the same generation. Trim level alone does not affect fitment in the way colour or interior finish would, but confirm the exact variant with the breaker against your registration to be sure you're getting the right unit.

Yes — nearside (NS, passenger side) and offside (OS, driver side) shock absorbers are handed and not interchangeable, so always tell the breaker which side you need. Fitting the wrong side is a straightforward mistake to avoid, and any reputable breaker will ask you this before quoting.

Both a 2004 and a 2010 SLK sit within the R171 generation (2004–2011), so they share the same basic platform, but 2004 is the opening year of that generation and there may be early-build differences in suspension specification. Confirm with the breaker against both registrations, and mention your engine size, before agreeing the sale.
