The Bilstein B8 8100 Bypass Reservoir Shocks Rear Pair are high-performance, externally adjustable shocks designed for light trucks and SUVs. Featuring dual-tube external bypass technology, these shocks provide position-sensitive damping with independent rebound and compression adjustments, allowing precise tuning for various driving conditions. Constructed with a 60mm large bore hard anodized aluminum piston, they deliver enhanced damping control and long-term durability. The shocks utilize Bilstein’s twin-tube technology and gas-pressure design to prevent oil foaming and damping fade under extreme stress, ensuring consistent performance. The package includes all necessary washers, bushings, nuts, and reservoir mounts, with factory shock mounting bolts reused for installation. An optional billet aluminum reservoir clamp is available for a cleaner, more compact appearance, making these shocks ideal for off-road and performance applications.

Designed to fit 2003–2024 Toyota 4Runner models with factory height or up to 2" rear lift, these shocks are compatible with both 4WD and RWD configurations. They exclude vehicles equipped with XREAS, which must be removed for compatibility. Suitable for vehicles with no suspension modifications or minor lift systems, these shocks are a direct bolt-on upgrade that enhances ride quality, bottom-out control, and off-road capability. The externally adjustable bypass feature allows for easy tuning, making them suitable for off-road enthusiasts, daily drivers, and performance-focused users seeking maximum bottom-out control and a compliant ride in rough terrain. The package provides a rear pair of shocks ready for installation, ensuring optimal suspension performance.

  • Fits 4WD & RWD vehicles
    This product works for 4WD and RWD vehicles.
  • Reservoir Mounts Included
    All necessary washers, bushings, and nuts included. Factory shock mounting bolts are reused for installation. An optional billet aluminum reservoir clamp is available for a more clean and compact look.
  • Adjustable Rebound & Compression
    Dual tube external bypass offers position sensitive damping with independent adjustment for rebound and compression.
  • Durable Design
    60mm large bore hard anodized aluminum piston provides a greater ranger of damping control and long term durability.
  • Bilstein twin-tube technology
    Twin-tube shocks utilize double-walled technology, where the piston divides the interior oil chamber into two working chambers. Under load, the piston pushes the oil down through the inner working chamber and up into the outer chamber. During rebound, the oil flows back through the piston valve to create a damping effect.
  • Bilstein Gas-Pressure Technology
    Traditional oil shock absorbers, when put under extreme stress, can lead to oil foaming which causes shock fading and results in damping power reduction. In the 1950s Bilstein found the solution to this problem by developing gas-pressure technology.

Bilstein B8 8100 (Bypass) is a direct fit, position sensitive damper specifically designed for light trucks and SUVs. Bypass shock absorbers offer the most compliant ride in all conditions and provide maximum bottom out control when the road gets rough. Utilizing an adjustable external bypass shock is the easiest and most effective way to tune your suspension for ultimate performance. Incremental flow adjuster offers finite and incremental changes in damping force for precise adjustments.
