A Part That Fails Quietly, Then Suddenly

On the Fiat 500 Classic, rear spring sag tends to creep in gradually over months, with little more than a slightly lower ride height to show for it, before ending suddenly at the coil's end with an audible clunk — worth remembering if one rear corner starts sitting noticeably lower than the other.

Before you buy: drivetrain, trim, and left/right side all affect spring rate and fitment. Always confirm against your VIN before ordering.

Accuracy note: Covers the Fiat 500 Classic (2007- petrol 500) 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 SP3816 (standard, 274 mm); Sachs 994214 (standard, 276 mm); Febi Bilstein 46981 (274 mm); Suplex 09178 (275 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

The Fiat 500 Classic's rear springs should always go in as a pair — fitting one new spring alongside an old, sagged one on the opposite side leaves the car sitting unevenly and biases how it handles.

Fiat 500 Classic Rear Springs: What It Does

On the Fiat 500 Classic, supporting the rear end's weight and absorbing the first impact of a bump is the rear coil spring's job, working alongside the shock absorber rather than doing its job for it. A sagged or broken spring drops ride height, can throw off headlight aim, and in serious cases fails an MOT outright.
