Toyota C-HR Rear Springs: Specs, Fitment & Common Faults
Confirmed directly in Toyota's own parts catalogue: left and right rear coil springs are listed as genuinely separate parts, not a single item fitted either side.

Left and Right Are Genuinely Separate Parts — Confirmed by Toyota's Own Catalogue
Genuinely worth knowing: Toyota's own parts catalogue lists rear coil springs as lower-left and lower-right references — distinct, non-interchangeable parts rather than a single spring fitted to either side. Where AWD is offered on this model, AWD and front-wheel-drive versions also use different springs, reflecting the different rear subframe and driveline layout.
Toyota C-HR Rear Springs: 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 — worth bearing in mind if you notice one rear corner sitting lower than the other. Toyota's own guidance notes that coil springs aren't especially prone to failure under normal use, but cutting, clamping, or heating a spring (sometimes done to lower ride height) genuinely compromises it and can lead to premature failure.

OEM Part Number: confirm via VIN — rear coil springs (aftermarket) Monroe SP4889 / Sachs 992473
| Rear coil springs (aftermarket) | Monroe SP4889 (398 mm); Sachs 992473; Suplex 35580 (standard, 405 mm); Stark SKCS-0040452 (370 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 |
| Non-hybrid, lower right | Genuinely a different part number from the lower-left spring, and potentially from the hybrid version below — confirm side and powertrain before ordering |
| Non-hybrid, lower left | A genuinely different reference from the lower-right spring above |
| Hybrid, where distinct from non-hybrid | Confirm via VIN — some generations share references between hybrid and non-hybrid, others use a hybrid-specific spring |
Replacing just one Toyota C-HR rear spring is a false economy: pairing it with an old, sagged spring on the other side produces uneven ride height and a noticeable handling bias.
Toyota C-HR Rear Springs: What It Does
The Toyota C-HR's rear end weight rests on the coil spring, which also absorbs the initial shock of a bump — a separate function from the shock absorber, not a replacement for it. Left sagged or broken, it lowers ride height, potentially skews headlight aim, and can become an MOT failure in severe cases.
