The ICON IIC Alternate Function Plug Kit allows for the seamless integration of CDEV secondary shocks to an ICON CDEV suspension system. The addition of secondary shocks allows for a dramatic increase in shock damping for maximum off-road performance. This plug and play wire harness installs easily and the ICON IIC app will automatically detect the secondary shocks without having to perform any software updates. The IIC app functionality allows for different baseline shock settings for the secondary shocks from the primaries, allowing a wide range of shock tuning options to suite the terrain and your driving style.This Part Fits: Year Make Model Submodel 2017-2024 Ford F-250 Super Duty King Ranch 2017-2024 Ford F-250 Super Duty Lariat 2018-2024 Ford F-250 Super Duty Limited 2017-2024 Ford F-250 Super Duty Platinum 2017-2024 Ford F-250 Super Duty XL 2017-2024 Ford F-250 Super Duty XLT 2017-2024 Ford F-350 Super Duty King Ranch 2017-2024 Ford F-350 Super Duty Lariat 2018-2024 Ford F-350 Super Duty Limited 2017-2024 Ford F-350 Super Duty Platinum 2017-2024 Ford F-350 Super Duty XL 2017-2024 Ford F-350 Super Duty XLT
