Bilstein 5100 series gas pressurized shocks feature a monotube design to run cooler and operate more efficiently to help prolong service life. A 46mm digressive piston with a self-adjusting valve adjusts instantly to varying road conditions, providing superior handling and performance across all types of terrain. Bilstein 5100 series shocks are tuned for each specific application rather than using a one-size-fits-all valving profile. Zinc plated finish with Triple-C technology coating. Sold individually with a black dust boot, bushings where required, and installation hardware. Limited lifetime warranty.
