Second Hand Mercedes-Benz CLS Coil Spring

The CLS does use coil springs on many variants — it is not exclusively an air-suspension car, though some higher-spec or AMG-line variants were offered with optional air suspension or AIRMATIC. If you are unsure which setup your car has, check underneath or look for a suspension mode button in the cabin, as a coil-spring part will not suit an air-suspension car. Confirm with the breaker which type your car runs before ordering.

Almost certainly not without verification — the first-generation CLS (W219, 2004–2010) and the second-generation CLS (W218, 2011–2017) are built on different platforms with different suspension geometry. These are distinct generations and parts are not expected to cross over, so always quote your exact generation to the breaker. Never assume a spring from a W219 will suit a W218 or vice versa.

Yes, engine size can influence spring specification because heavier engines place different loads on the front suspension in particular, so a V8 CLS 500 or CLS 63 AMG may carry a stiffer or heavier-rated front spring than a four-cylinder or straight-six variant. When contacting a breaker, always tell them your exact engine — for example CLS 220d, CLS 350 or CLS 63 AMG — as well as your generation. Do not assume any CLS spring from the same year will fit regardless of engine.

Trim names like AMG Line are primarily cosmetic designations and do not in themselves change the spring specification — what matters is the actual engine fitted and whether the car has standard or sport suspension. However, sport suspension variants may carry different spring rates to standard cars built in the same period, so confirm with the breaker whether the donor car's suspension setup matches yours. Trim badges alone are not a reliable guide to which spring is correct.

The W218 CLS was facelifted in 2014, and while the basic platform remained the same, it is not certain that suspension components cross freely across that model-year boundary without verification. Name the facelift year to the breaker and ask them to check the donor car's build date against yours, as there can be mid-generation running changes. Do not assume pre- and post-facelift springs are interchangeable — route this to the breaker to confirm against your registration.

Yes, on the CLS the left and right springs must be matched to the correct side, particularly at the rear where spring perch angles and load paths can differ. Always tell the breaker which corner you need — nearside (left, kerb side) or offside (right, driver's side) — and whether it is front or rear. Fitting a spring to the wrong corner can affect ride height and handling, so getting the side right is not optional.
