      Extreme All-Terrain Performance. Take your 3 to 4.50-inch lifted Wrangler JL’s handling performance to the extreme with the Bilstein B8 8100 Bypass Series Rear Driver Side Shock for a 3 to 4.50-Inch Lift. This rear driver side shock combines a gas-charged monotube design with a remote reservoir and advanced external bypass technology. These factors work to provide you with immediate damping response and extreme handling control. Furthermore, this shock also features velocity-sensitive digressive valving that works to provide a more controlled but no less comfortable ride quality on the highway. This way, you’re still able to use your Jeep as a daily driver.

      Independent Compression and Rebound Adjustment. This 8100 series rear shock’s external bypass technology also includes independent compression and rebound adjustment. This is done by turning knobs on the bypass tubes, enabling you to fine-tune compression and rebound. This allows you to get the right amount of damping response for your needs.

      Durable Build Quality. This rear damper’s shock body features a 60mm internal bore design and is machine-formed from high-quality aluminum. This combination of large bore and aluminum construction works to efficiently dissipate heat, preventing fade. Additionally, its 18mm piston rod is crafted from chrome-hardened alloy, offering superior strength for the trails. Lastly, this assembly is zinc plated before getting finished in a clear topcoat for maximum corrosion protection.

      Hassle-Free Install Procedure. This rear driver side shock is designed to mount onto your Jeep’s factory counterpart’s location without the need for drilling or other modifications. Also, installation is completed using just basic hand tools to complete.

      Backed by a Limited 2-Year Warranty. This B8 8100 rear shock is backed by a limited 2-year warranty covering factory defects. Please visit the manufacturer’s website for more details.

      Application. The Bilstein B8 8100 Bypass Series Rear Driver Side Shock for 3 to 4.50-Inch Lift fit all 2018 to 2021 Jeep Wrangler JL 4-Door models.
