Icon Vehicle Dynamics 61721E 2.5 VS Remote Reservoir CDEV Front Coilover Reservoir Adjustable Shock Lift 4-5.5" Ford F-250/F-350 17-26 Pair

ICON 2.5 VS Series Remote Reservoir Bolt-In Coilover Conversion Kit

The ICON 2.5 VS Series Remote Reservoir Bolt-In Coilover Conversion Kit adds enhanced damping performance and adjustable ride height for 2017–2025 F-250 and F-350 trucks. Based on ICON’s 2.5 VS Series shock platform, the kit features ICON-engineered coil springs, FK rod end bearings, vehicle-specific valving, precision machined components, and a fully serviceable design for rebuilds and retuning. The ICON CDEV (Compression Damping Electronic Valve) upgrade is included to allow in-vehicle electronic tuning of compression damping.

The CDEV is an electronically controlled valve that meters oil flow to regulate compression damping. It is infinitely variable, can react in less than 40 ms, and provides precise adjustments across varying terrain. When paired with ICON Intelligent Control and the ICON mobile app, CDEV uses onboard G-force and gyroscope data plus user-defined settings to predict terrain and actively adjust shock behavior.
