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

The Bilstein B8 8100 Rear Passenger-Side Remote-Reservoir Shock is engineered for drivers who demand reliable suspension performance during aggressive off-road driving and extended overland travel. Its large-bore design helps maintain precise control when conditions become increasingly demanding.

The remote reservoir and 2.65-inch shock body significantly increase oil volume, helping dissipate heat more effectively than conventional shocks. This promotes consistent damping during long trail days and repeated cycling.

Bilstein's monotube architecture and velocity-sensitive digressive valving automatically adapt to terrain. Vehicle-specific tuning improves ride quality, handling, and control across pavement, gravel, and technical off-road obstacles.

The bottom port reservoir hose provides additional bottom-out control during compression, while the incremental flow adjuster allows fine damping adjustments to match driving conditions, vehicle weight, and vehicle build setup..

From rocky trails and washboard roads to overland expeditions, the B8 8100 Rear Passenger-Side Remote-Reservoir Shock delivers the durability, consistency, and performance expected from Bilstein's off-road suspension lineup.
