Bilstein B8 8100 Bypass Shock Absorber (MPN: 25-326369)

Advanced adjustable bypass design for enhanced suspension performance.

The Bilstein B8 8100 Bypass Shock Absorber is engineered for light trucks and SUVs, providing a direct fit and position-sensitive damping. This shock absorber features an adjustable external bypass design that allows for independent tuning of compression and rebound, ensuring optimal performance across various driving conditions. The nitrogen gas charged system enhances ride quality while maintaining control during rough terrain, making it a reliable choice for off-road enthusiasts.

With a robust 18 millimeter piston rod and a 60 millimeter large bore hard anodized aluminum piston, the B8 8100 delivers exceptional durability and a smoother ride by reducing internal gas force ramp-up. The bottom port reservoir hose increases bottom-out control during compression, allowing for a more compliant ride. The incremental flow adjuster provides precise adjustments to damping force, catering to specific vehicle dynamics and driver preferences.

Installation is straightforward due to the direct fit design, and the shock absorber is built with a billet rod end and vulcanized mounts for long-term reliability. The Bilstein B8 8100 is a single unit that does not include shock boots, and its gray body color adds a sleek aesthetic to your vehicle's suspension system.
