Mercedes-Benz SLK Aerial Replacement Parts

Yes, the SLK has a roof-mounted or fin-style aerial for radio reception, and on some variants this is a powered retractable unit built into the front wing area or a fixed shark-fin style depending on generation. All variants of the SLK were fitted with some form of aerial, so there is a genuine used part to source. The type fitted can vary between generations, so it is worth identifying exactly which style is on your car before requesting quotes.

The R170 (1996–2004) and R171 (2004–2011) are distinct generations with different body panels and aerial mounting points, so the aerial from an R170 is very unlikely to be a straight swap onto an R171. The R170 commonly used a retractable electric aerial mounted in the front wing, while the R171 moved toward a fixed fin-style unit, meaning the mounting, wiring connector, and aperture will differ. Confirm the exact type and fitment with the breaker against your registration before buying.

The R171 received a facelift in 2008, but aerial design and mounting on this generation did not change significantly at that point, so a pre-facelift and post-facelift R171 aerial are generally compatible. That said, wiring connector design can occasionally differ between build dates, so it is sensible to confirm with the breaker using your registration to be certain. This is a low-risk cross-boundary swap, but worth a quick check before committing.

The R172 (2011–2020) is a completely different generation from the R171 (2004–2011) and uses different body panels and mountings, so the aerials are not interchangeable. The R172 uses a shark-fin aerial integrated into the roof panel, which is a fundamentally different design and fixing method to the R171 unit. You will need to source a part specifically from the correct generation for your car.

Trim level and engine variant do not affect aerial fitment on the SLK — the aerial is the same part regardless of whether your car is an SLK 200, SLK 250, SLK 300, or an AMG Line specification. What matters is the generation (R170, R171, or R172) and the specific aerial type fitted to your car, which you can confirm from the existing unit. If in doubt, share your registration with the breaker so they can match the exact part.

Mercedes-Benz shark-fin aerials can sometimes be shared across models of the same era because the mounting base and connector can be common across the range, but this is not guaranteed — roof curvature and fixing points differ between models. It is a reasonable avenue to explore if an SLK-specific unit is hard to find, but you should confirm the donor car's roof profile and connector type with the breaker against your specific registration before purchasing.
