BILSTEIN 41-284568 Front Left Shock Absorber B8 8112 (R3) for TOYOTA 4Runner 4x4

Description BILSTEIN 41-284568 Front Left Shock Absorber B8 8112 (R3) for TOYOTA 4Runner 4x4

The BILSTEIN B8 8112 ZoneControl® CR suspension kit integrates advanced position-sensitive damping technology into a direct-fit coilover system. Developed to deliver exceptional comfort during everyday driving while maintaining maximum control under extreme suspension inputs, this kit combines innovative internal damping architecture with vehicle-specific tuning. The result is a suspension solution capable of adapting seamlessly to both street use and demanding off-road conditions.

ZoneControl® CR utilizes a triple-piston design to manage damping forces independently in compression and rebound. Three compression zones and two rebound zones are controlled by internal pistons, allowing the suspension to progressively adapt as travel increases. The internal compression and rebound stops eliminate the need for external hydraulic bump stops or limit straps, improving reliability, packaging, and overall suspension performance.
