Bilstein B8 5160 Remote Reservoir Shock Absorber 25-311211

The Bilstein B8 5160 remote reservoir shock absorber, part number 25-311211, is engineered as a direct-fit suspension upgrade for lifted trucks and SUVs. Its remote reservoir increases cooling capacity and available wheel travel, helping optimize suspension performance during demanding off-road driving. Designed for light-truck applications, this shock absorber is compatible with select 2011–2014 Toyota FJ Cruiser, 2012–2014 Toyota 4Runner, and 2012–2014 Lexus GX460 models.
The 46mm monotube design delivers consistent, fade-resistant performance by maintaining reliable damping control under changing conditions. Velocity-sensitive digressive valving is tuned for the specific application to provide responsive handling on the road and controlled suspension movement over uneven terrain. The non-adjustable damping configuration offers a straightforward installation without requiring manual tuning.
A 360-degree swivel banjo hose fitting helps simplify hose positioning and supports a clean, low-profile installation. The included billet reservoir clamp securely mounts the remote reservoir, while the zinc-plated smooth body provides durable protection for demanding environments. A black bellows boot helps protect the shock shaft from dirt and debris, and the eye lower mount with stem upper mount supports the intended vehicle-specific fitment.
This Bilstein B8 5160 shock absorber features a 14mm shaft, 9.00 inches of suspension travel, a 14.50-inch collapsed length, and a 23.50-inch extended length. It includes a remote reservoir and is designed without a spring seat for non-coilover applications. Professional installation is recommended, and fitment should be verified against the vehicle’s suspension configuration before ordering.
