BMW Air Spring - Bilstein B3 40-221595

Product Information

An air suspension spring (also called an air spring or airbag) is a flexible rubber and fabric component used in place of traditional coil springs. It is inflated with compressed air to support the vehicle’s weight and adjust ride height. Air springs are commonly found in luxury cars, SUVs, and heavy-duty vehicles.

• Vehicle sagging – one corner, one side, or the whole car sits lower than normal.
• Rough or bouncy ride – loss of cushioning, making the vehicle feel harsh over bumps.
• Air compressor running constantly – the system tries to compensate for leaking or failed air springs.
