A Part That Fails Quietly, Then Suddenly

A 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 Hybrid4 variants, a lower rear ride height than a standard petrol/diesel equivalent can be a normal characteristic of the added rear motor weight rather than purely a sign of sagged springs.

Before you buy: Hybrid4 vs standard petrol/diesel and generation both affect spring rate and fitment. Always confirm against your VIN before ordering.

OEM Part Number: confirm via VIN — no aftermarket rear spring listed for this generation

Accuracy note: Covers the Citroen C5 Aircross (2018-) as listed in the UK aftermarket catalogues. Rear coil springs are sold as a pair for the axle and should be replaced as a pair, because a new spring beside a tired one leaves the car sitting unevenly. The right spring depends on the engine and gearbox, the suspension type (standard, sport or heavy-duty) and, on some cars, the body style. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives; carmakers rarely publish the genuine number against these, so match a genuine spring against your VIN if you want a guaranteed fit. genuinely worth knowing: rear springs are sold in left/right pairs matched to a specific rate marking — confirm the marking on your existing spring rather than assuming from trim or powertrain alone.

Rear coil springs (aftermarket)	No aftermarket rear coil spring listed for this generation — order genuine against your VIN
Genuine (OE) numbers quoted	None quoted in the catalogue listings — the genuine spring varies by engine, suspension type and body style, so order it against your VIN
Standard petrol/diesel	Genuinely a different spring from the Hybrid4 version below — confirm powertrain before ordering
Hybrid4	A genuinely different spring rate from the standard petrol/diesel version, reflecting the rear-mounted electric motor's effect on weight distribution

Fitting the Citroen C5 Aircross'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.

Citroen C5 Aircross Rear Springs: What It Does

The Citroen C5 Aircross'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.
