Bilstein 19-20 BMW 330i / 19-20 330i xDrive / 20 M340i / 20 M340i xDrive B6 Performance Shock Rear

This Bilstein B6 Performance rear shock absorber uses a monotube design, which helps keep the fluid and gas separated to maintain consistent damping performance. It's built to work with your vehicle's original factory springs, so you don't need to buy new ones to get an improved ride. This shock is a direct replacement for the rear of many BMW models, including the 330i, 430i, and M340i.

The application-specific valving in these shocks is tuned to bring out the best handling characteristics of your BMW. Whether you're navigating daily traffic or facing more demanding driving situations, you can expect better grip and more stable lane changes. Bilstein's gas-pressure technology is a key part of how these shocks achieve improved safety and performance without requiring a spring change.

If you're looking to restore or enhance the handling of your BMW 330i, 430i, M340i, or M440i, these rear shocks are a solid option. They meet or exceed OE quality standards, offering a well-built upgrade that focuses on improving your driving experience.
