GX460 2010-2023 Lexus 4WD (w/0-2.5" lift) - Bilstein REAR Adjustable B8 8100 (DSA) Series Shock

25-294101 Bilstein B8 8100 (DSA) Reservoir Shock Absorber is a high-performance suspension upgrade designed for Lexus GX460 models equipped with lifted suspension systems. Built for demanding off-road environments and long-distance travel, this large-bore 60mm shock absorber provides exceptional damping control, heat management, and durability when navigating rough terrain.

The Bilstein B8 8100 series features a large 60mm piston and shock body that significantly increases oil capacity to better manage heat during aggressive driving conditions. Constructed from aerospace-quality billet components, the monotube design delivers consistent, fade-resistant performance while Bilstein’s velocity-sensitive digressive valving ensures optimal ride comfort and control across varying terrain.

This shock incorporates Bilstein’s Dual Speed Adjustment (DSA) system, allowing independent tuning of both low-speed and high-speed compression using external click adjuster knobs. The result is precise suspension tuning that can be tailored to different driving environments, whether navigating rocky trails, high-speed desert terrain, or everyday road use.

A remote or piggyback reservoir configuration further increases oil capacity and cooling efficiency while maintaining a direct-fit installation for lifted trucks and SUVs. The Bilstein B8 8100 (DSA) shock absorber provides the strength, adjustability, and performance needed to confidently tackle demanding off-road conditions while maintaining excellent on-road ride quality.
