Bilstein 34-050149 Suspension Strut Cartridge - Front

Bilstein B6 Performance Front Strut Cartridge

The Bilstein B6 Performance front strut cartridge, part number 34-050149, is a suspension upgrade for drivers who want sharper handling while retaining the OE factory spring. Built with application-specific valving and a monotube internal design, it is engineered to improve control, safety, and response on the road.

Compatible with 1986-1991 Mazda RX-7 front applications, this Bilstein Shock Absorbers component is a direct-fit performance option for the original strut housing after modification. The yellow-painted finish identifies the B6 Performance series and reflects Bilstein’s established OE-level testing standards.

B6 Performance Series Details

Bilstein B6 Performance dampers are tuned as an OE spring pairing, making them a practical choice for restoring or improving suspension behavior without changing the factory spring setup. The monotube construction helps maintain consistent damping response, while the application-specific valve settings are matched to the vehicle platform for more controlled handling.
