Upgrade the front suspension of select Toyota 4Runner and Lexus GX460 applications with the Bilstein B8 8112 ZoneControl CR front left corner module. Part number 41-324158 is a direct-fit coilover assembly engineered for light trucks and SUVs, combining adjustable ride height with position-sensitive damping. The result is a suspension system that delivers controlled, comfortable performance during everyday driving while maintaining composure when the vehicle encounters larger suspension inputs.
The ZoneControl CR system uses a triple-piston design with three independent pistons to manage three compression zones and two rebound zones. This position-sensitive damping technology allows the coilover to respond differently across the suspension stroke, helping provide a more comfortable ride over smaller road irregularities and increased control during demanding off-road or heavily loaded conditions. The threaded spring seat allows application-dependent ride-height adjustment, making it possible to fine-tune the vehicle’s stance and suspension setup.
A remote reservoir increases oil capacity and helps improve heat management during extended use. The included bolt-on, anodized reservoir chassis mount provides a secure installation solution while maintaining a clean, application-specific layout. As a complete front left corner module, this Bilstein assembly is designed to simplify installation compared with sourcing individual suspension components. The B8 8112 ZoneControl CR is a suitable performance upgrade for select Toyota 4Runner models from 2010 through 2015 and Lexus GX460 models from 2010 through 2011; verify vehicle application and corner position before ordering.
