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

The Bilstein B8 8112 ZoneControl CR DSA+ Front Driver-Side Remote-Reservoir Coilover is designed for advanced suspension control with the ability to fine-tune performance for different driving conditions. Combining Bilstein's position-sensitive damping technology with user-adjustable settings, it provides a highly adaptable suspension solution for both daily driving and demanding off-road use.

ZoneControl CR DSA+ builds upon Bilstein's position-sensitive damping system by adding dual-speed adjustability. This allows drivers to make precise changes to suspension behavior through easy-to-access click adjuster knobs.

A triple-piston design delivers three stages of compression valving and two stages of rebound valving, allowing for smooth compliance while maintaining the support needed for large impacts, aggressive trails, and high-load situations.

The integrated adjusters provide control; Low-speed adjustments help fine-tune body control, steering response, and overall handling, while high-speed adjustments help manage larger impacts, such as whoops and trail obstacles.

An adjustable JCO internal hydraulic bump stop system provides additional support. This helps improve impact control, reduce harsh bottom-out events, and maintain confidence when pushing the vehicle through demanding terrain.
