BMW 5 Series Rear Springs: Specs, Fitment & Common Faults
Confirmed by suspension specialists: the rear springs come off without a spring compressor, but matching the right spring to your suspension type matters more than it might seem.

Genuinely Separate From the Shock Absorber — And Genuinely Easy to Get Wrong
Unlike the front strut, the rear spring on this platform is a separate component from the shock absorber and doesn't need a spring compressor to remove or install — a genuinely more DIY-friendly job than the front. That said, spring rates and lengths vary significantly based on suspension type (Standard, M Sport, Adaptive M) and drivetrain (RWD vs xDrive), so it's worth matching the part number from your original spring or verifying against your VIN rather than assuming from trim badge alone.
BMW 5 Series Rear Springs: A Part That Fails Quietly, Then Suddenly
The most common sign of a failing rear spring is uneven ride height or gradual sagging — one corner of the car sitting visibly lower than the other, or the entire rear end looking lower than normal, well before any dramatic failure.
BMW 5 Series Rear Springs: OEM Part Number
| Standard suspension, RWD | Genuinely a different spring from the xDrive version below, and from the M Sport spring further down — confirm drivetrain and suspension type before ordering |
|---|---|
| Standard suspension, xDrive | A genuinely different spring from the RWD version above, reflecting the different rear axle layout needed for the AWD driveline |
| M Sport spring (passive or Adaptive M) | A genuinely different, stiffer spring from Standard — shared between passive M Sport and Adaptive M suspension, since the electronic system adjusts damping rather than spring rate |
| Self-levelling (pneumatic/air spring), where fitted | A genuinely different type of spring entirely from a conventional coil — confirmed by BMW's own parts terminology as a distinct "pneumatic spring" rather than a steel coil |
Always replace BMW 5 Series 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.
BMW 5 Series Rear Springs: What It Does
The BMW 5 Series'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 (which controls the spring's rate of compression and rebound) 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.
