A Part That Fails Quietly, Then Suddenly

It's a slow decline followed by a sudden failure with the Peugeot 108's rear springs — a gradually lower ride height for months, then an abrupt break at the coil's end announced by a clunk. One rear corner sitting visibly lower than the other is the sign to watch for.

Before you buy: generation and body style both affect spring rate and fitment. Always confirm against your VIN before ordering.

Accuracy note: Covers the Peugeot 108 (2014-) 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)	Kilen 51449; Monroe SP4301 (standard); Suplex 07197 (324 mm); KYB K-Flex RA5216 (311 mm)
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

It's worth doing the Peugeot 108's rear springs as a pair rather than one at a time — mixing a new spring with an old, sagged one on the opposite side throws off ride height evenly and skews handling.

Peugeot 108 Rear Springs: What It Does

On the Peugeot 108, weight support at the rear and absorbing a bump's first impact both fall to the coil spring, working in tandem with the shock absorber rather than substituting for it. A broken or sagged spring drops ride height, can affect headlight alignment, and in bad cases is enough to fail an MOT.
