Lexus RX Rear Springs: Specs, Fitment & Common Faults

Hybrid and non-hybrid versions carry genuinely different weight, and the rear spring rate reflects that.

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.

Before you buy: hybrid vs non-hybrid and left/right side both affect 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.

Petrol/non-hybrid, standard rate	Genuinely a different spring from the hybrid version below — confirm powertrain and side before ordering
Hybrid	A genuinely different spring rate from the non-hybrid version, reflecting the different weight distribution of the hybrid drivetrain
F Sport, where fitted	A genuinely different, stiffer spring from standard trims

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.
