Peugeot 508 Rear Springs: Specs, Fitment & Common Faults

Hybrid4's rear-mounted electric motor genuinely changes rear weight distribution enough to affect the spring rate.

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 Hybrid4 variants, a lower rear ride height than a standard petrol/diesel equivalent can be a normal characteristic of the added rear motor weight rather than purely a sign of sagged springs.

Before you buy: Hybrid4 vs standard petrol/diesel and generation both affect spring rate and fitment. Always confirm against your VIN before ordering.

Accuracy note: 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.

Always replace 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.

What It Does

The 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.
