ICON 53509 Intelligent Control IIC Install Kit for 2024+ Toyota Tacoma, Land Cruiser 250, and 4Runner

ICON Intelligent Control (IIC) is the computer that monitors, analyzes, and processes data in real-time. Information from the onboard G-force sensor and Gyroscope perform calculations based on algorithms and user-defined settings to predict terrain and wheel position. IIC has the capability to collect information at over 1000 times per second, process the data and make adjustments, then deliver those changes to Compression Damping Electronic Valve (CDEV) in the shock absorbers in under 40 milliseconds. IIC also works as a data driver to connect the user to ICON’s proprietary mobile App interface for monitoring and adjusting shock settings. The IIC is mounted to the 2024-2026 Toyota Tacoma, 2024-2026 Toyota Land Cruiser 250 Series, and 2025-2026 Toyota 4Runner using application specific mounting brackets, hardware and wire harnesses, ensuring an easy and clean looking install.

The ICON Intelligent Control (IIC) Install Kit, part number 53509, provides the application-specific components needed to install ICON’s advanced electronic shock control system on select Toyota vehicles. Designed for the 2024–2026 Toyota Tacoma, 2024–2026 Toyota Land Cruiser 250 Series, and 2025–2026 Toyota 4Runner, the kit includes vehicle-specific mounting brackets, hardware, and wire harnesses for a clean, organized installation. The system is not compatible with vehicles equipped with Adaptive Variable Suspension (AVS).
ICON IIC functions as the control center for compatible ICON electronic suspension systems. Its onboard G-force sensor and gyroscope monitor vehicle movement and terrain in real time, using custom algorithms and user-defined settings to predict wheel position and calculate appropriate damping adjustments. The system processes sensor information more than 1,000 times per second and can send commands to Compression Damping Electronic Valve (CDEV) shock absorbers in less than 40 milliseconds, helping maintain responsive suspension control as driving conditions change.
The ICON IIC also connects to the ICON IIC Mobile App through Bluetooth and an iOS device, allowing the driver to select preconfigured Drive Modes or create custom suspension presets. Baseline settings can be adjusted manually without leaving the vehicle, while integrated data-logging functions record trip information such as time, speed, distance, and G-force. With its dedicated installation hardware and vehicle-specific wiring, the ICON 53509 kit supports a streamlined setup for enhanced control and monitoring of compatible Toyota suspension applications.
