ICON Vehicle Specific (V.S.) 3.0 Series Shocks

ICON 3.0 Series shocks are vehicle-specific, length- and tune-matched monotube shocks engineered for outstanding off-road performance and a smooth on-road ride. The 3.0 Series features a larger piston area and increased oil volume for improved stability, heat dissipation, and resistance to shock fade under hard use. These shocks are 100% rebuildable and 100% revalveable.

CDE Valve (Compression Damping Electronic Valve) is included to allow electronic in-vehicle adjustment of compression damping. The CDEV meters oil flow to regulate damping force, reacts in less than 40 ms, and provides precise, application-specific hydraulic tuning. When used with ICON Intelligent Control, the system adjusts settings dynamically based on onboard sensors and user-defined parameters.

Key Features

• Compatible with 0–3.5" of front lift over stock (application dependent)
• Vehicle-specific design and tuning for superior damping and control
• 3.0" body diameter for increased oil volume and larger piston area
• Extended travel length requires ICON Delta Joint Pro front upper control arms and provides maximum wheel travel
• Internal “Bump Zone” increases damping by 20% to help control harsh bottom outs and high-velocity compression
• Nitrogen-charged monotube design with remote reservoir for improved heat dissipation and reduced shock fade
• CDE Valve technology enables in-vehicle adjustment and active control via ICON Intelligent Control
• Premium grade 5WT shock oil for consistent damping across a wide temperature range
• One-piece linear compression / digressive rebound piston with vehicle-specific valving for balanced on- and off-road performance
• 7/8" induction-hardened, chrome-plated shock shaft
• Press-in, bonded rubber bushing / bar pin assembly for OE-type fitment and vibration damping
• 6061 aircraft-grade aluminum CNC-machined components
• Cerakoted steel cylinders for corrosion resistance and consistent finish
• 100% rebuildable and 100% revalveable

Notes

• Shocks are fully serviceable. Lift heights indicated are for a stock-equipped vehicle.
• ICON Delta Joint Pro upper control arms required.
• An iOS-operated device is required to run the ICON Intelligent Control app.
• Also requires installation of the applicable IIC kit and CDEV rear shocks.
• Compatible with 0–3.5" of front lift on most Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD submodels; compatible with 0–2" of front lift on Chevrolet Silverado 2500 ZR2 and GMC Sierra 2500 AT4X.
