Mazda 3 Rear Springs: Specs, Fitment & Common Faults

Confirmed by suspension specialists: FWD and AWD Mazda 3s use completely different rear axle designs, and that extends to the spring, not just the shock.

Confirmed: FWD Torsion Beam vs AWD Multi-Link

Genuinely important to establish before ordering: FWD Mazda 3s use a simpler, more compact torsion beam rear suspension, while AWD versions use a more complex multi-link independent rear suspension to accommodate the rear driveshafts — the spring seat and spring rate genuinely differ between the two architectures, not just the shock absorber.

Worth knowing about the current generation's platform: the current Mazda 3 (and related CX-30, CX-50) uses a torsion beam rear axle across the range as a cost-driven change from the previous generation's multi-link setup — confirm your exact generation before assuming which architecture applies.

Mazda 3 Rear Springs: A Part That Fails Quietly, Then Suddenly

It's a slow decline followed by a sudden failure with the Mazda 3'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 (FWD/AWD) and generation both determine rear axle type and spring fitment. Always confirm against your VIN before ordering.

OEM Part Number: confirm via VIN — rear coil springs (aftermarket) Monroe SP4606 / Sachs 992298

Accuracy note: Covers the Mazda 3 (BM 2013-2019) 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: confirm your exact FWD (torsion beam) or AWD (multi-link) configuration before ordering, since the spring seat design genuinely differs between the two.

Rear coil springs (aftermarket)	Monroe SP4606 (standard, 371 mm); Sachs 992298 (standard, 373 mm); Febi Bilstein 185270 (367 mm); Suplex 17196 (standard, 373 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
FWD (torsion beam)	Genuinely a different spring and spring seat design from the AWD version below — not interchangeable between drivetrains
AWD (multi-link)	Genuinely a different spring from the FWD torsion-beam version, reflecting the completely different rear axle architecture

It's worth doing the Mazda 3'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.

Mazda 3 Rear Springs: What It Does

On the Mazda 3, 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.
