FJ Cruiser 2007-2014 Toyota - Bilstein REAR Adjustable B8 8100 (DSA) Series Shock

25-350500 Bilstein B8 8100 (DSA) Reservoir Shock Absorber improves suspension control and off-road performance on 2007–2014 Toyota FJ Cruiser models equipped with lifted suspension systems. Engineered for demanding off-road conditions and long-distance travel, this large-bore performance shock delivers increased damping capacity, improved heat management, and precise adjustability for a wide range of terrain.

The Bilstein B8 8100 series features a large 2.65" diameter shock body and 60mm piston that significantly increases oil capacity to manage heat during aggressive off-road use. Built from aerospace-quality billet components, the monotube design provides consistent, fade-resistant performance, while Bilstein’s velocity-sensitive, digressive valving delivers controlled damping tuned specifically for the vehicle.

This B8 8100 (DSA) version includes Dual Speed Adjustment, allowing independent tuning of high- and low-speed compression via external click-adjuster knobs. This system allows precise suspension tuning to match different driving conditions, from rocky trails and desert terrain to highway driving with added load.

A remote or piggyback reservoir design further improves cooling efficiency and overall shock performance. The large piston design enhances stability and ride comfort while maintaining excellent suspension control in both on-road and off-road environments.
