Product Details
The Bilstein B4 front left strut assembly for the 2021-2025 BMW M4 restores the ride the car left the factory with. When the original dampers wear out a car floats over crests and patters over broken pavement. This is the fix.
B4 DampTronic dampers are direct replacements for the factory electronically adjustable dampers. They are built to restore the original ride quality and handling, and to meet or exceed original equipment standards.
Bilstein invented the monotube gas damper and has built suspension in Germany since 1954. The same engineering that goes into their original-equipment contracts goes into this part, and it carries a limited lifetime warranty.
Features
- High power reserves for maximum safety
