What is the main benefit of the remote reservoir on this shock?

The remote reservoir increases the shock's oil capacity. This extra oil helps dissipate heat more effectively, leading to more consistent damping performance and reduced fade during demanding off-road use.

What type of valving does the Bilstein B8 5165 use?

This shock absorber features self-adjusting deflective disc valving. This advanced valving system reacts immediately to changes in the terrain, helping to maximize vehicle control.

What are the mounting eyelets like on this shock?

The B8 5165 shock absorbers come equipped with 5/8 inch eyelets. These are fitted with hourglass bushings on both ends to ensure a solid and durable connection point.

About this part

Product Details

Bilstein is well-known for their high-performance suspension components, and the B8 5165 remote reservoir shock absorber is a prime example for custom off-road builds. This shock is built to handle the demands of light trucks and SUVs tackling tough terrain. Its monotube design, combined with a remote reservoir, is key to maintaining consistent performance even when the going gets rough.

What sets this shock apart is the remote reservoir. It holds extra shock oil, which helps dissipate heat more effectively than a standard shock. This means less fade and more consistent damping, especially during extended off-road use. The self-adjusting deflective disc valving reacts quickly to changes in the road or trail surface, giving you better control. Plus, the unique 360-degree swivel banjo hose fitting makes for a cleaner, more streamlined installation on your custom setup.

With its 46mm monotube construction and the added cooling capacity from the remote reservoir, this Bilstein shock is built for durability in harsh off-road environments. It comes with 5/8 inch eyelets and hourglass bushings for a solid connection.
