The ICON Vehicle Dynamics Electronic Shock Simulator Kit allows for the installation of ICON or other aftermarket coilovers on 2021-2024 Chevrolet Tahoe/Suburban and GMC Yukon/Yukon XL equipped with Magnetic Ride Control to provide an increase in ride height and improved suspension performance. These electronic shock simulators send the return signal to the vehicles computer, making it think the OE shocks are still installed, and allow full systems functionality without error codes or warning lights on the dash. This kit is complete with a set of (4) shock simulators, enough for one complete vehicle, and easily installs into the vehicle’s OE shock wiring harnesses in a simple, plug and play manner.
