What is the benefit of a remote reservoir shock absorber?

A remote reservoir holds more shock oil than a standard shock. This allows for greater heat dissipation, which helps prevent performance fade during extended or hard use, especially off-road.

What does the 46mm monotube design do?

The monotube design separates the oil and gas, which helps maintain consistent damping performance and prevents aeration. This leads to more reliable control and less fade in demanding conditions.

Does this shock come with mounting hardware?

This shock absorber includes 5/8 inch eyelets with hour glass bushings on both ends. Specific mounting hardware for your custom application may need to be sourced separately based on your vehicle's setup.

About this part

Product Details

The 46mm monotube design in this Bilstein B8 5165 shock absorber is key to its consistent performance, especially when you're pushing your light truck or SUV off-road. This shock is built for custom applications where you need more from your suspension than stock parts can offer. It’s designed to give you that specific ride you’re aiming for, handling the demands of harsh environments.

What really sets this shock apart is the remote reservoir. It holds more shock oil, which means better heat dissipation and less chance of fade during hard use. This improved cooling capacity directly translates to more reliable performance and increased wheel travel, helping you conquer tough terrain. The unique 360-degree swivel banjo hose fitting is a smart touch, allowing for a clean, low-profile installation without getting in the way. Plus, the self-adjusting deflective disc valving reacts quickly to changes in the surface, giving you better control over your vehicle.

This shock absorber comes with 5/8 inch eyelets and hour glass bushings on both ends, making it ready for many custom setups. If you're building a custom off-road vehicle and need a shock that can handle more, this Bilstein unit is a solid option.
