A Part That Fails Quietly, Then Suddenly

It's a slow decline followed by a sudden failure with the Fiat 500X'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: drivetrain, trim, and left/right side all affect spring rate and fitment. Always confirm against your VIN before ordering.

OEM Part Number: confirm via VIN — rear coil springs (aftermarket) Monroe SP4481 / Sachs 992120

Accuracy note: Covers the Fiat 500X (2015-) 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)	Monroe SP4481 (332 mm); Sachs 992120 (standard); Suplex 09259 (standard, 326 mm); KYB K-Flex RA5384 (334 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
Front-wheel drive, standard rate	Genuinely a different spring from the AWD version below — confirm drivetrain and side before ordering
AWD	A genuinely different spring from the front-wheel-drive version, reflecting the different rear axle layout

It's worth doing the Fiat 500X'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.

Fiat 500X Rear Springs: What It Does

On the Fiat 500X, 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.
