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 Prius 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.
Toyota Prius Rear Springs: OEM Part Number
| 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 |
Always replace Toyota Prius 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.
Toyota Prius Rear Springs: What It Does
The Toyota Prius'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.
