Bilstein ZoneControl CR DSA+ Front Left Coilover Shock

The Bilstein B8 8112 ZoneControl CR DSA+ coilover shock (also called a coil-over shock and spring assembly or corner module) is a direct-fit, vehicle-specific suspension upgrade. It is built for light trucks and SUVs. It combines position-sensitive damping with user-adjustable compression, so the ride stays comfortable every day and the suspension stays controlled over rough terrain.

Key Features:

• ZoneControl CR position-sensitive damping: a triple piston design gives three stages of compression valving and two stages of rebound valving. The ride stays comfortable in normal driving, and damping firms up under large suspension inputs.
• Dual Speed Adjustable (DSA+) compression: click adjusters let you set low-speed and high-speed compression separately.
• Adjustable JCO internal bump stop: a hydraulic compression stop improves bottom-out control and reduces the need for an external bump stop.
• Internal rebound stop: it absorbs spring energy after large compression events and helps prevent harsh top-out.
• Remote reservoir: it adds oil capacity and cooling for consistent damping under demanding use.
• Threaded spring seat: it allows ride height adjustment, within the range set for each application.
• Complete module: the spring comes pre-loaded to the recommended ride height, so installation is easier.
• Vehicle-specific engineering: aerospace-quality components are tuned to each application to optimize wheel travel and clearance.
• Serviceable: the shock is rebuildable and revalvable, which extends its service life.

Bilstein's monotube, gas-charged damper technology is proven in motorsport and off-road use. The B8 8112 ZoneControl CR DSA+ series suits drivers who want an adjustable, high-performance suspension without giving up daily-driving comfort.
