What does the ZoneControl R DSA technology do?

ZoneControl R DSA technology uses a double piston system to provide position-sensitive rebound damping. This helps eliminate harsh suspension top-out events and allows for precise, click-adjustable tuning of both low and high-speed compression for a tailored ride.

Do I need to buy anything else to install this shock?

This shock absorber is designed as a direct fit for lifted applications and includes a remote reservoir. It's generally recommended to install shocks in pairs on the front axle for balanced performance. Refer to the manufacturer's installation instructions for any specific hardware or tool requirements.

How does the large 60mm piston benefit my ride?

The larger 60mm piston in this shock absorber allows for more fluid displacement and better heat dissipation. This translates to improved comfort and more consistent control, especially during demanding driving conditions or when carrying loads.

About this part

Product Details

If you're looking to dial in the suspension on your 2019-2025 Ram 2500 with a 2 to 2.5-inch front lift, this Bilstein B8 8100 ZoneControl R DSA shock absorber for the front right is a solid option. This large 60mm bore monotube shock is built to handle the demands of lifted trucks, offering a direct fit installation without needing external limit straps thanks to its position-sensitive rebound damping technology.

What really sets this shock apart is the adjustability. You get easy-to-use click adjuster knobs that let you precisely tune both low-speed and high-speed compression. This means you can really tailor the ride to different surfaces, whether you're on the highway or tackling rougher terrain. The ZoneControl R technology uses a double piston design to manage rebound damping based on the shock's position, which helps eliminate harsh top-out events. The large 60mm piston also contributes to a more comfortable ride and better control in various driving conditions, and the monotube design ensures consistent performance without fade.

This shock absorber comes with a remote reservoir, making installation straightforward. It's designed to work with your lifted Ram 2500's suspension, providing a noticeable improvement in ride comfort and control. For the best results, it's recommended to install these in pairs on the front axle.
