Kia Niro Rear Springs: Specs, Fitment & Common Faults

Genuinely worth knowing: the hybrid's extra battery weight is a real engineering consideration for the rear spring, even where a lower-than-expected ride height might otherwise look like sagging.

A Part That Fails Quietly, Then Suddenly

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. On hybrid variants, a lower rear ride height than a non-hybrid equivalent can be a normal characteristic of the added battery weight rather than purely a sign of sagged springs — worth bearing this in mind before assuming a fault.

Before you buy: hybrid vs non-hybrid, drivetrain, 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 SP5008 / Sachs 992452

Accuracy note: Covers the Kia Niro (2016-2022) 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 or powertrain alone.

Rear coil springs (aftermarket)	Monroe SP5008 (365 mm); Sachs 992452 (standard, 373 mm); Suplex 46153 (standard, 373 mm); Eibach R23237 (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
Petrol/non-hybrid, standard rate	Genuinely a different spring from the hybrid version below — confirm powertrain and side before ordering
Hybrid	May carry a different spring rate to help support the added battery weight — confirm via VIN rather than assuming the non-hybrid spring is a like-for-like fit

Always replace Kia Niro 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.

Kia Niro Rear Springs: What It Does

The Kia Niro'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.
