Mercedes-Benz E-Class Rear Springs: Specs, Fitment & Common Faults
On AIRMATIC cars, there's genuinely no conventional coil spring at the rear at all — an air spring does the job instead.

Steel Coil or Air Spring — Confirm Which Your Car Has First
Genuinely important to establish before ordering: standard models use a conventional steel rear coil spring, while AIRMATIC-equipped cars replace it entirely with an air spring integrated into the rear shock assembly — there's no separate steel coil to order on an AIRMATIC car. The existence of genuine aftermarket conversion kits (AIRMATIC to complete strut-and-coil-spring assemblies) confirms just how different these two systems really are, rather than one being a stiffer variant of the other.
Mercedes-Benz E-Class Rear Springs: A Part That Fails Quietly, Then Suddenly
A conventional rear spring often sags gradually for months without an obvious symptom beyond a slightly lower ride height, then fails suddenly at the coil's end with an audible clunk. On AIRMATIC cars, a failing air spring more commonly shows up as a dashboard suspension warning and the car settling to a lower ride height overnight as air leaks out.
Mercedes-Benz E-Class Rear Springs: OEM Part Number
| Standard steel-spring, right | Genuinely a different part number from the left-side spring — confirm side before ordering |
|---|---|
| Standard steel-spring, left | A genuinely different reference from the right-side spring above |
| Higher Ground Clearance Springs (factory option), where fitted | A genuinely different, taller spring from the standard-trim version — a distinct factory option code, not a standard part |
| AIRMATIC, all variants | No standalone coil spring exists — the air spring is integrated into the rear shock assembly; see the Rear Shock Absorber guide for the correct part |
Always replace steel rear springs in pairs — a single new spring paired with an old, sagged one on the other side creates an uneven ride height and handling bias.
Mercedes-Benz E-Class Rear Springs: What It Does
On standard cars, the rear coil spring supports the weight of the car's rear end and absorbs the initial impact of a bump, working alongside the shock absorber rather than replacing its function. On AIRMATIC cars, an air spring performs this role instead, with the added ability to adjust ride height automatically. A sagged or broken steel spring lowers ride height, can affect headlight aim, and in severe cases is an MOT failure item.
