Coil spring

BMW coil springs rarely have problems—they’ll typically outlast the car.

Pneumatic springs are prone to leaks caused by punctures and splits—this is a common problem in vehicles with air suspension. It is important to fix replace leaking units promptly as they’ll quickly overwork (and kill) the compressor.

Coil springs absorb most of the rear axles vertical movement—with the rest being absorbed by the shock absorbers and arms.

Pneumatic springs replace coil springs in air suspension systems—and they significantly improve the ride quality.

In some BMW suspension systems, the rear springs are combined with the shock absorbers to form struts—this applies to both coil and air suspension systems.

We don’t sell many coil springs—but as we understand it, they’re relatively generic within a model generation.

We do sell plenty of pneumatic springs though—and there can be multiple different options within to account for different engine types and suspension packages.

The best way to determine fitment compatibility of a pneumatic spring is to match the BMW part numbers from the catalogue. This can be done by decoding your vehicle’s VIN in a BMW EPC (electronic part catalogue.)

If you don’t have access to an EPC, provide our team with your vehicle’s 17-digit VIN—and we’ll check our stock for a compatible match.

There is limited interchangeability between models for both coil springs & pneumatic springs.
