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

The remote reservoir holds extra shock oil, which increases the overall cooling capacity. This helps prevent the shock from overheating and fading during heavy use, leading to more consistent performance.

How does the valving in this shock absorber work?

This shock features velocity-sensitive digressive valve settings that are tuned for your specific vehicle. It reacts immediately to surface changes, allowing for maximum vehicle control and a more stable ride.

Does this shock absorber come with all the necessary hardware for installation?

While the shock absorber includes a unique 360-degree swivel banjo hose fitting, it's always recommended to check the manufacturer's installation instructions for a complete list of included hardware and any additional items you might need for proper installation.

About this part

Product Details

Bilstein is well-known for making solid suspension components, and their 5160 Series shocks are a popular choice for trucks that see a lot of action, especially off-road. This rear shock absorber is built specifically for your 2011-2018 Ram 1500 4WD, and it's designed to give you more capability when you leave the pavement behind.

What sets this shock apart is the remote reservoir. It holds extra shock oil, which helps keep things cooler under heavy use. This means more consistent performance and less fading, even when you're pushing your truck hard. The monotube design also contributes to this consistent performance, reacting quickly to changes in the road or trail thanks to its velocity-sensitive digressive valving, which is tuned specifically for your Ram 1500. You'll also find a unique 360-degree swivel banjo fitting on the hose, making installation cleaner and more low-profile.

This shock absorber is a well-built option that can handle tougher off-road conditions, giving you improved durability and control when you need it most.
