A Part That Fails Quietly, Then Suddenly

Months of gradual sagging with barely any symptom beyond a marginally lower ride height is the usual pattern for the Citroen C4 Cactus's rear spring, right up until it fails suddenly at the coil's end with a clunk. If one rear corner looks lower than the other, that's the clue worth acting on.

Before you buy: generation and body style 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 C4 Cactus (2014-2020) 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 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 rate	Confirm your exact generation and side, since PSA Group used multiple distinct rear spring references across most model generations
Estate/higher-load body style, where applicable	Genuinely a stiffer rear spring rate than the equivalent standard body style, to handle the increased load-carrying capacity

Replacing just one Citroen C4 Cactus rear spring is a false economy: pairing it with an old, sagged spring on the other side produces uneven ride height and a noticeable handling bias.

Citroen C4 Cactus Rear Springs: What It Does

The Citroen C4 Cactus's rear end weight rests on the coil spring, which also absorbs the initial shock of a bump — a separate function from the shock absorber, not a replacement for it. Left sagged or broken, it lowers ride height, potentially skews headlight aim, and can become an MOT failure in severe cases.
