Bilstein 25-326369 B8 8100 Bypass Rear Left Shock Absorber for Toyota 4Runner and Lexus GX460

Bilstein B8 8100 (Bypass) is a direct fit, position sensitive, damper for light trucks and SUV’s. These motorsports inspired shock absorbers utilize a dual tube externally adjustable bypass design. B8 8100 (Bypass) feature “Incremental Flow” bypass adjusters, allowing for finite and incremental changes for rebound and compression. The shocks utilize a bottom hose, remote reservoir exit port, delivering increased compression control during the full cycle. The remote reservoir is supplied with a bolt-on aluminum anodized chassis mount for an easy fitment. BILSTEIN B8 8100 (Bypass) will maximize the driver experience, offering unparalleled ride comfort and incredible bottom out control. 60mm Shock Absorber

• 60mm large bore hard anodized aluminum piston offers a greater range of damping control and delivers exceptional long-term durability
• Dual tube external bypass offers position sensitive damping with independent adjustment for rebound and compression
• Incremental flow adjuster offers finite and incremental changes in damping force for precise adjustments

Upgrade the suspension performance of your light truck or SUV with the Bilstein B8 8100 Bypass Rear Left Shock Absorber, part number 25-326369. Designed as a direct-fit replacement for listed Toyota 4Runner and Lexus GX460 applications, this motorsports-inspired damper combines position-sensitive control with externally adjustable rebound and compression settings. It is engineered to improve ride quality, handling stability, and bottom-out control during demanding on-road and off-road driving.
The Bilstein B8 8100 uses a dual-tube external bypass design that allows damping characteristics to change according to suspension position. Incremental Flow bypass adjusters provide finite, repeatable tuning changes, helping drivers refine suspension response for different terrain, vehicle loads, and driving conditions. A bottom hose and remote reservoir exit port help maintain consistent compression control through the full suspension cycle, while the remote reservoir supports additional damping capacity and tuning flexibility.
The remote reservoir includes a bolt-on, anodized aluminum chassis mount to simplify installation and provide a secure mounting solution. A large-bore, hard-anodized aluminum piston is built for long-term durability and offers a broad range of damping control. This rear left shock absorber is a practical choice for drivers seeking enhanced suspension performance without sacrificing everyday ride comfort. Professional installation and suspension tuning are recommended to ensure proper fitment and optimal performance for the vehicle and intended use.
