Overview

The Bilstein B8 8100 Rear Remote-Reservoir Shock is designed for 4Runner owners who demand premium suspension performance during serious off-road use. Developed with Bilstein's large-bore shock technology, it delivers enhanced control, durability, and consistency when traveling over rough terrain for extended periods.

Performance

Featuring a massive 2.65-inch shock body, the B8 8100 helps manage heat buildup during prolonged suspension cycling, maintaining reliable damping performance during long trail runs, desert driving, and heavily loaded adventures.

Advantage

The external reservoir further improves thermal management under demanding conditions. The reservoir hose design also provides additional bottom-out control during the compression cycle for improved impact management.

Technology

The monotube design utilizes Bilstein's velocity-sensitive digressive valving. This allows the shock to provide comfortable ride quality during everyday driving while delivering the control needed for larger suspension inputs off-road.

Capability

Vehicle-specific tuning combined with the incremental flow adjuster allows fine adjustments. This provides greater control over suspension behavior and allows drivers to tailor performance based on vehicle setup and driving style.
