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

The remote reservoir increases the shock absorber's oil capacity. This allows for better heat dissipation, which helps prevent shock fade and optimizes performance, especially during extended use or in demanding off-road conditions.

How does the monotube design contribute to performance?

A monotube design separates the shock oil from the nitrogen gas charge. This helps maintain consistent damping performance and prevents the shock from fading, even under heavy use or high temperatures.

Does this shock absorber come with all the necessary mounting hardware?

This shock absorber includes a unique 360-degree swivel banjo hose fitting and an attractive billet reservoir mount where applicable, designed for a clean installation. Refer to the manufacturer's instructions for a complete list of included hardware.

About this part

Product Details

The 46mm monotube design in this Bilstein 5160 Series shock absorber is key to its consistent performance, especially when you're pushing your 2014-2025 Ram 2500. This design helps prevent the shock from fading, even under tough conditions, which is crucial for maintaining control whether you're on the highway or tackling rough terrain.

What really sets this shock apart is the remote reservoir. It holds extra shock oil, allowing for better heat dissipation. This means the shock can work harder for longer without overheating, giving you more wheel travel and better overall performance, particularly for lifted trucks. The unique 360-degree swivel banjo hose fitting and billet reservoir mount also make for a clean and low-profile installation, so it looks as good as it performs.

Bilstein tunes these shocks specifically for each application, so you get valving that reacts immediately to surface changes, enhancing vehicle control. This shock absorber is built to increase durability, helping your Ram 2500 handle demanding off-road environments with more confidence.
