Bilstein ZoneControl R DSA Reservoir Shock Absorber

The Bilstein B8 8100 (ZoneControl R DSA) reservoir shock absorber is an adjustable, large-bore 60mm direct-fit shock for lifted trucks and SUVs. Click adjuster knobs let you set both low-speed and high-speed compression damping, so you can tune the ride for different surfaces.

Key Features:

• Dual Speed Adjustment: Click adjuster knobs give precise, separate control of low-speed and high-speed compression.
• ZoneControl R technology: A double-piston design provides position-sensitive rebound damping. It helps prevent harsh suspension top-out events and removes the need for an external limit strap.
• Reservoir design: Each shock uses a remote or piggyback reservoir for a simple installation.
• Monotube construction: Gives consistent, fade-resistant performance.
• Velocity-sensitive digressive valving: Valve settings are tuned for each specific application.
• Large 60mm piston: Adds comfort and control in a wide range of driving conditions.

Bilstein is known for monotube damper technology. The B8 8100 series is built for drivers who want adjustable ride comfort and control on and off the road. Choose the correct part number for your application.
