Bilstein B8 8100 ZoneControl R reservoir shock absorbers deliver position-sensitive rebound damping to eliminate harsh top-out events on light trucks and SUVs.

Engineered for heavy-duty performance and everyday drivability, this suspension system combines advanced double-piston valving with remote reservoir cooling to maintain stability under heavy loads.

• Direct Fit and Full Compatibility: Designed specifically for light trucks and SUVs, these 60mm shock absorbers integrate seamlessly into your vehicle without requiring major fabrication or suspension modifications.
• Eliminates Harsh Top-Out Events: ZoneControl R technology provides position-sensitive rebound damping that actively prevents severe suspension top-outs, removing the need for an external limit strap and protecting your suspension components.
• Advanced Double-Piston Valving: The 2-stage rebound valving system offers unparalleled ride comfort during daily driving while providing maximum control and stability over large off-road suspension inputs.
• Enhanced Remote Reservoir Cooling: Supplied with a high-pressure braided hose, the system includes a bolt-on, anodized aluminum reservoir chassis mount to increase fluid cooling capacity and prevent shock fade under heavy use.
• Heavy-Duty Material Construction: Built with a hardened chrome piston rod and an anodized reservoir housing, these imported shock absorbers resist corrosion and endure harsh environmental conditions for long-term durability.
• Optimized Physical Profile: Each unit measures 32 inches in length, 14 inches in width, and 6 inches in height, weighing 19.4 pounds to ensure proper suspension geometry and effective load management.
