Product Details
Bilstein B4 shocks bring the 2020-2021 BMW M340i (G20/G21) back to its factory ride. When the original dampers wear out a car starts to float over crests and patter over broken pavement, and this is the fix.
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
- High power reserves for maximum safety
- Restores original driving comfort, handling and safety
- High OE quality
