Mercedes-Benz CLA Rear Springs: Specs, Fitment & Common Faults
No AIRMATIC option on this model — every version uses a conventional steel rear coil spring, but that doesn't mean every spring is the same.

A Straightforward Steel Spring — With Genuine Trim and Drivetrain Variants
Unlike the RWD-based C/E-Class/GLC range, the CLA doesn't offer AIRMATIC air suspension — every version uses a conventional steel rear coil spring. Spring rate still genuinely differs by trim and drivetrain, though: 4MATIC (all-wheel-drive) versions use a different spring from front-wheel-drive variants, and AMG Line/AMG-badged cars use a stiffer spring again.
Mercedes-Benz CLA Rear Springs: A Part That Fails Quietly, Then Suddenly
On the Mercedes-Benz CLA, the typical failure pattern here is gradual sag over months, barely noticeable beyond a marginally lower stance, followed by a sudden break at the coil's end with an audible clunk. If one rear corner appears to be sitting lower than the other, that's worth investigating.
Mercedes-Benz CLA Rear Springs: OEM Part Number
| Front-wheel drive, standard rate | Genuinely a different spring from the 4MATIC and AMG versions below — confirm drivetrain and trim before ordering |
|---|---|
| 4MATIC (all-wheel drive) | A genuinely different spring from the front-wheel-drive version, reflecting the different rear axle layout |
| AMG Line/AMG, where fitted | A genuinely different, stiffer spring from standard trims |
Fitting the Mercedes-Benz CLA's rear springs one at a time tends to backfire: pairing a fresh spring with a sagged original on the other side leaves the car sitting unevenly and biases handling to one side.
Mercedes-Benz CLA Rear Springs: What It Does
The Mercedes-Benz CLA's rear coil spring carries the weight of the car's back end and takes the first hit from any bump, working alongside — not instead of — the shock absorber. Once it sags or breaks, expect a lower ride height, possible headlight aim issues, and in severe cases, an MOT failure.
