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

The remote reservoir increases the shock absorber's oil capacity. This allows for better heat dissipation, which helps prevent performance fade during extended or hard use, and also enables greater wheel travel.

What kind of installation can I expect with this shock?

This shock absorber features a unique 360-degree swivel banjo hose fitting. This design helps provide a clean, low-profile installation, which is often important for custom builds where space can be tight.

What does the monotube design offer?

The 46mm monotube design is known for its consistent and fade-free performance. It helps maintain stable damping characteristics across a variety of conditions, especially during demanding off-road driving.

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 of their expertise for custom off-road builds. This shock is built to help you achieve a specific ride quality on your light truck or SUV, offering improved cooling and more wheel travel thanks to its remote reservoir design. It’s a monotube shock absorber, meaning it uses high gas pressure to ensure consistent performance, even when you're pushing your vehicle hard.

What sets this shock apart is the remote reservoir, which holds extra shock oil. This extra capacity helps dissipate heat more effectively, preventing fade during demanding off-road use. The self-adjusting deflective disc valving reacts quickly to changes in the terrain, giving you better control. Plus, the unique 360-degree swivel banjo hose fitting allows for a clean and low-profile installation, which is crucial when you're building a custom rig. The 5/8 inch eyelets with hour glass bushings on both ends are built solid for durability in harsh environments.
