The Bilstein B6 Performance front strut cartridge is a monotube gas pressure insert that drops into the original strut housing and replaces the worn damper element, so the housing, spring, and mounts stay on the car. Valving is calibrated for the application and works with the factory springs, which leaves ride height unchanged while restoring body control and damping consistency over a tired OE damper. The high pressure gas charge keeps oil and gas separated to resist foaming and fade under repeated compression. Each cartridge measures 17.13 in collapsed and 21.99 in extended, uses a stem upper mount with a base cup lower mount, and is finished in yellow paint with a blue bellows boot.
