Bilstein B8 8100 Rear Shock Absorber for 2003-2024 Toyota 4Runner and Lexus GX460/GX470 (25-294095)

Fits select 2003-2024 Toyota 4Runner, 2010-2023 Lexus GX460, and 2003-2009 Lexus GX470 models.

The Bilstein B8 8100 is a high-performance, large-bore rear shock absorber designed as a direct-fit solution for lifted trucks and SUVs. Constructed with aerospace-quality billet components, the 2.65-inch OD shock body provides significantly higher oil volume capacity than standard units, ensuring superior heat dissipation during long-distance travel over rough road surfaces. These shocks utilize a monotube design for consistent, fade-free performance and feature velocity-sensitive digressive valving tuned specifically for the 4Runner and Lexus GX chassis.

The B8 8100 includes a remote reservoir to increase oil capacity and cooling efficiency, allowing for exceptional comfort without sacrificing low-speed control. The large 60mm piston design delivers a wider range of tunability and helps tame technical terrain during demanding off-road use.
