The Bilstein B8 5160 remote reservoir shock absorber, part number 25-312157, is engineered as a direct-fit suspension upgrade for select lifted trucks and SUVs. Its remote reservoir increases cooling capacity and available wheel travel, helping maintain consistent performance during demanding off-road use. The zinc-plated smooth-body construction is designed for durability in harsh environments, while the application-specific tuning supports controlled handling and improved suspension response.
The 46mm monotube design delivers consistent, fade-resistant damping across changing conditions. Bilstein’s velocity-sensitive digressive valving is tuned for the specific vehicle application, providing responsive control over rough terrain without sacrificing road manners. The remote reservoir configuration also helps manage heat during extended use, making this shock absorber well suited for drivers who expect reliable performance on trails and uneven surfaces.
This Bilstein B8 5160 shock features a 360-degree swivel banjo hose fitting for flexible installation and includes a billet reservoir clamp for a clean, low-profile mounting solution. It uses a non-adjustable damping design, a 14mm shaft, a 16mm eye upper mount, and a stem-style lower mount. The shock has an 8.57-inch stroke, a 16.00-inch collapsed length, and a 24.57-inch extended length. It is designed for select Mercedes-Benz G-Class applications, including the 2004 G500 and G55 AMG, as well as 2005-2018 G500 and G550 models. Professional installation and verification of vehicle fitment are recommended.
