Bilstein B8 8100 Bypass Reservoir Shocks Rear Pair - 2003-2024 Toyota 4Runner 4WD RWD

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.
