Bilstein B8 8100 DSA Rear Remote-Reservoir Shock for 0.9–2.5 in Lift for Toyota 4Runner (2003–2024)

The Bilstein B8 8100 DSA Rear Remote-Reservoir Shock is designed for drivers who want professional-level suspension performance with the ability to adjust damping characteristics for different terrain and vehicle setups. Building on Bilstein's large-bore 8100 platform, it combines increased oil capacity with user-adjustable tuning for maximum versatility.

The monotube design uses Bilstein's velocity-sensitive digressive valving. Combined with vehicle-specific tuning, it delivers improved control, body movement, and dependable performance across a wide range of driving conditions.

The DSA system allows drivers to adjust suspension response through multiple damping settings, providing the ability to fine-tune compression, whether prioritizing comfort during driving or additional support during off-roading.

The B8 8100 DSA shock offers increased oil volume to better control operating temperatures during extended use. This helps maintain damping performance during long-distance trail runs, desert terrain, and heavily loaded adventures.

An incremental flow adjuster provides fine damping adjustments, allowing drivers to optimize behavior based on tire size, vehicle weight, and terrain. The reservoir hose design also helps improve bottom-out control during compression.
