# ICON 20-26 GM 2500/3500 HD IIC Install Kit

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 2020-2026 Chevrolet Silverado 2500/3500 HD or 2020-2026 GMC Sierra 2500/3500 HD using application specific mounting brackets, hardware and wire harnesses, ensuring an easy and clean looking install.
