Subaru Impreza Rear Springs: Specs, Fitment & Common Faults

Genuinely worth knowing: the rear spring and shock are commonly sold together as a complete assembly on Subaru's platform, not always as separate parts.

A Part That Fails Quietly, Then Suddenly

On the Subaru Impreza, the typical failure pattern here is gradual sag over months, barely noticeable beyond a marginally lower stance, followed by a sudden break at the coil's end with an audible clunk. If one rear corner appears to be sitting lower than the other, that's worth investigating.

Genuinely worth knowing: the rear spring and shock are commonly sold together as a complete strut assembly on this model rather than always as separate parts — check whether a listing is for the complete assembly or the spring alone before ordering.

Before you buy: turbo vs naturally aspirated, transmission type, and generation all affect fitment. Always confirm against your VIN before ordering.

OEM Part Number: confirm via VIN — no aftermarket rear spring listed for this generation

Accuracy note: Covers the Subaru Impreza (2017-) 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: Subaru's own parts catalogue can list separate rear spring references for automatic and manual transmission versions of the same engine, in addition to the turbo/non-turbo split.

Rear coil springs (aftermarket)	No aftermarket rear coil spring listed for this generation — order genuine against your VIN
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
Naturally aspirated, standard rate	Genuinely a different spring from the turbo version below — confirm engine and transmission before ordering
Turbo, where fitted	A genuinely different, typically stiffer spring from the naturally aspirated version

Fitting the Subaru Impreza's rear springs one at a time tends to backfire: pairing a fresh spring with a sagged original on the other side leaves the car sitting unevenly and biases handling to one side.

Subaru Impreza Rear Springs: What It Does

The Subaru Impreza's rear coil spring carries the weight of the car's back end and takes the first hit from any bump, working alongside — not instead of — the shock absorber. Once it sags or breaks, expect a lower ride height, possible headlight aim issues, and in severe cases, an MOT failure.
