Product Details
The Bilstein B6 struts sharpen the 2017-2020 BMW 440i xDrive (F32/F33) without touching its ride height. Firmer, more tightly controlled damping on the factory springs, so the car settles faster and stays flatter through a corner.
Bilstein has built suspension in Germany since 1954, and supplies the same engineering to manufacturers as original equipment. The build quality is the reason these outlast what they replace, and they are covered by a limited lifetime warranty.
Features
- Perfectly adapted to suit series-production electronic adjustment systems
- Ability to switch rapidly from comfort to sport setting
- Marked improvement in safety and performance with additional spring changes
