The Bilstein B8 8100 Bypass Reservoir Shocks Rear Pair are high-performance, external bypass shocks designed for light trucks and SUVs. Constructed with a 60mm large bore hard anodized aluminum piston, these shocks provide a wide range of damping control and long-term durability. Featuring dual tube external bypass technology, they offer position-sensitive damping with independent adjustment for rebound and compression, allowing precise tuning for various driving conditions. 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 kit includes reservoir mounts, washers, bushings, nuts, and reuses factory shock mounting bolts, with an optional billet aluminum reservoir clamp for a cleaner look.

These shocks are compatible with 2003-2023 Toyota 4Runner models at factory height or with up to 2" rear lift, suitable for both 4WD and RWD configurations. They are ideal for off-road, trail, or rough-road driving, providing maximum bottom-out control and a compliant ride. Installation is a direct bolt-on, with all necessary components included. Designed for vehicles with no suspension modifications or minor lifts, these shocks enhance off-road capability and ride quality by offering adjustable damping forces through an external incremental flow adjuster, making them suitable for enthusiasts seeking precise suspension tuning.

    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.
