ICON Intelligent Control Install Kit for 2020-2026 Silverado/Sierra 2500/3500 HD

The ICON Intelligent Control (IIC) Install Kit is an active suspension control module for 2020–2026 Chevrolet Silverado 2500/3500 HD and 2020–2026 GMC Sierra 2500/3500 HD trucks equipped with compatible ICON CDEV shocks. The IIC samples data from an onboard G-force sensor and gyroscope at over 1,000 times per second, processes that data through custom algorithms and user-defined settings, and delivers compression damping adjustments to CDEV shock absorbers in under 40 milliseconds.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Real-Time Damping Without Stopping

Because the IIC processes sensor inputs and pushes damping changes to the shocks in under 40 milliseconds, the suspension responds to terrain shifts before the driver would notice a need to adjust. That speed matters on washboard roads, sudden grade changes, or loaded hauls where a static damping setting is always a compromise. The IIC removes that compromise by continuously recalculating and acting on what the truck is actually doing.

Driver-Controlled Settings via the IIC App

The IIC connects to an iOS device over Bluetooth, giving the driver access to baseline firmness, G-Boost (vertical sensitivity), and Corner Boost (lateral sensitivity) without leaving the cab. Three preconfigured Drive Modes (Normal, Desert, and Haul) cover the most common use cases, and an unlimited number of custom presets can be saved for specific routes or loads. The app also logs time, speed, distance, and G-force data for each trip.

Application-Specific Hardware for a Clean Install

The kit includes mounting brackets, hardware, and wire harnesses designed specifically for the 2020–2026 Silverado 2500/3500 HD and Sierra 2500/3500 HD, so no fabrication or generic adapters are needed. The application-specific fit keeps wiring routed cleanly and the module mounted securely.

Specifications

Who This Is For and Isn't

The IIC Install Kit is for 2020–2026 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD owners who have already installed, or are installing, compatible ICON CDEV front and rear shocks and want active, app-controlled damping adjustment. It suits drivers who regularly switch between unladen highway driving, loaded hauls, and off-road use and want the suspension to adapt to each condition.

The IIC Install Kit does not include CDEV shocks. Compatible ICON CDEV front and rear shocks are required for the system to function and must be purchased separately. The IIC app requires an iOS device; Android is not supported. This kit does not fit any vehicle outside the 2020–2026 Silverado 2500/3500 HD and Sierra 2500/3500 HD application.

Common Questions

Do the CDEV shocks come with this kit?

The ICON IIC Install Kit does not include CDEV shocks. Compatible ICON CDEV front and rear shocks are required for the system to function and must be purchased separately. The IIC module controls damping through those shocks once they are installed.

Does the IIC app work on Android phones?

The IIC app requires an iOS device. Android is not supported. The app connects to the IIC module via Bluetooth and is used to adjust damping settings, select Drive Modes, create custom presets, and review trip data.

What vehicles does this install kit fit?

The ICON IIC Install Kit fits 2020–2026 Chevrolet Silverado 2500/3500 HD and 2020–2026 GMC Sierra 2500/3500 HD trucks. The included mounting brackets, hardware, and wire harnesses are designed specifically for those applications and do not fit other vehicles.

What does the IIC actually do while driving?

While driving, the IIC reads its onboard G-force sensor and gyroscope at over 1,000 times per second, runs those inputs through algorithms and the driver's saved settings, and sends compression damping adjustments to the CDEV shocks in under 40 milliseconds. The result is suspension damping that responds to terrain and load changes in real time rather than staying fixed at a single setting.

What is included in the California Proposition 65 warning for this product?

The ICON IIC Install Kit carries a California Proposition 65 warning stating that the product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents.
