Bilstein B8 8112 ZoneControl CR Front Driver-Side Remote-Reservoir Coilover with 1.3–4 in Lift for 4th-Gen 4Runner (2003–2009)

The Bilstein B8 8112 ZoneControl CR Front Driver-Side Coilover represents Bilstein's most advanced direct-fit suspension technology for the 4th-Gen 4Runner. Designed to deliver exceptional ride quality without compromising off-road capability, it adapts to changing suspension movement with remarkable precision.

At the heart of the system is Bilstein's innovative ZoneControl CR position-sensitive damping technology. Unlike conventional dampers that rely solely on shaft velocity, ZoneControl CR adjusts damping based on suspension position.

The advanced triple-piston architecture creates three stages of compression valving and two stages of rebound valving. This design allows the suspension to respond differently throughout its travel, improving small-bump compliance.

A threaded spring seat allows precise front adjustment from approximately 1.3 to 4 inches of lift. This gives owners the flexibility to accommodate larger tires, improve ground clearance, and fine-tune vehicle stance for their build.

The remote reservoir increases shock oil volume to improve heat dissipation during extended off-road use. By reducing operating temperatures, the system maintains more consistent damping characteristics during long trail days.
