FJ Cruiser 2007-2014 Toyota (w/0 to 2" lift) - Bilstein REAR B8 8100 Series Shock

25-350494 Bilstein B8 8100 Reservoir Shock Absorber improves suspension control and off-road performance on 2007–2014 Toyota FJ Cruiser models equipped with lifted suspension systems. Designed for demanding off-road conditions and long-distance travel, this large-bore performance shock delivers greater damping capacity, improved heat management, and consistent ride quality over rough terrain.

The Bilstein B8 8100 series utilizes a large 2.65" diameter shock body and 60mm piston that increases oil capacity to better manage heat during extended off-road use. Built from aerospace-grade billet components, the monotube design provides fade-free performance while Bilstein’s velocity-sensitive digressive valving delivers controlled damping tuned specifically for the application. A remote or piggyback reservoir design further improves cooling capacity and shock performance during aggressive driving conditions. This configuration helps maintain consistent damping performance across rough terrain while supporting heavier loads and lifted suspension setups commonly found on off-road vehicles.

Engineered as a direct-fit upgrade, the Bilstein B8 8100 reservoir shock absorber provides exceptional durability, comfort, and control across a wide range of driving environments. The large-piston design enhances overall suspension stability while delivering improved ride quality on both the highway and the trail.
