This is a pair of Bilstein rear springs for a Mercedes SLK R170. They have never been fitted and are brand new but I have had them in storage for a while. I bought them to replace the rear springs on my wifes car because one of the coils was broken. But as the mot tester never noticed it I never got round to fitting them and we no longer have the car. They are a premium quality replacement for the standard springs, they give the standard ride height.

I believe they also fit the Chrysler Crossfire and some other Mercedes models. But please check the part number in the Bilstein catalogue to be sure they are right for your car.
