Want suspension that actually reacts to how and where you drive your HD truck? The ICON 2.5 Aluminum Series Front Shock with Remote Reservoir and CDEV takes ride control to the next level with electronic compression tuning. Instead of a fixed shock setup that forces you to compromise between comfort and performance, this system lets you adjust damping on the fly based on road conditions, load, or driving style. Factory shocks can’t keep up when things get rough or when the truck is working hard, but this setup keeps the front end controlled, stable, and predictable in every scenario.

Built around ICON’s 2.5” aluminum-bodied V.S. shock platform, this system uses a remote reservoir design to increase oil capacity and improve heat dissipation, helping maintain consistent damping performance under sustained use. The aluminum construction keeps weight down while improving corrosion resistance, and the monotube internal design ensures precise, repeatable damping response.

The key feature here is ICON’s CDEV (Compression Damping Electronic Valve) system, which electronically adjusts oil flow through the shock in real time, reacting in milliseconds to changing terrain and driver input. This allows a wide range of tuning without manual adjustment, giving you a highly adaptable suspension setup for mixed-use trucks. Combined with heavy-duty internal components, rebuildable construction, and vehicle-specific valving, this shock is built for long-term durability while delivering high-end performance control on GM HD platforms.
