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

The remote reservoir holds extra shock fluid, which increases the shock's oil capacity. This allows for better heat dissipation, leading to more consistent and fade-free performance, especially during demanding off-road use or heavy hauling.

Is this shock absorber designed for stock height trucks?

The Bilstein 5160 Series shocks are specifically designed as a direct fit solution for lifted trucks and SUVs. They are intended to work with suspensions that have been raised from their original height.

What does the monotube design do for performance?

A monotube design separates the oil and gas within the shock absorber. This helps prevent foaming and ensures consistent damping performance, reducing the chance of fade even under heavy use.

About this part

Product Details

If you've lifted your 1999-2018 Chevrolet Silverado 1500 or GMC Sierra 1500 and need a rear shock that can keep up, this Bilstein 5160 Series shock absorber is a solid option. It's built to handle the demands of off-road driving and provide improved performance over stock, especially with a lifted suspension.

What sets this shock apart is the remote reservoir. It holds extra shock fluid, which helps dissipate heat more effectively. This means you get consistent, fade-free performance even during hard use, like driving on rough trails or hauling heavy loads. The monotube design also contributes to this consistent performance, reacting quickly to changes in the road surface to give you better control. Bilstein tunes these shocks specifically for applications like yours, ensuring the digressive valving works well with lifted trucks.

Installation is made cleaner with a unique 360-degree swivel banjo hose fitting and a billet reservoir mount, which tucks away neatly. This shock absorber is designed to increase overall durability, letting you tackle tougher terrain with more confidence.
