Mazda 6 Rear Springs: Specs, Fitment & Common Faults

Genuinely worth confirming first: drivetrain and left/right side both affect which rear spring fits.

A Part That Fails Quietly, Then Suddenly

On the Mazda 6, a rear spring often sags gradually for months without an obvious symptom beyond a slightly lower ride height, then fails suddenly at the coil's end with an audible clunk — worth bearing in mind if you notice one rear corner sitting 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 Mazda 6 (GJ 2012-) 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 56056; Monroe SP5182 (345 mm); Abakus 234-02-245; Denckermann D700604
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

Always replace Mazda 6 rear springs in pairs — a single new spring paired with an old, sagged one on the other side creates an uneven ride height and handling bias.

Mazda 6 Rear Springs: What It Does

The Mazda 6's rear coil spring supports the weight of the car's rear end and absorbs the initial impact of a bump, working alongside the shock absorber rather than replacing its function. A sagged or broken spring lowers ride height, can affect headlight aim, and in severe cases is an MOT failure item.
