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

ICON V.S. 3.0 Series shocks are vehicle-specific, application-tuned dampers engineered to deliver strong off-road performance while maintaining a smooth on-road ride. Built with a larger piston and increased oil capacity, these monotube remote-reservoir shocks improve stability, heat dissipation and resistance to shock fade under heavy use. Fully serviceable and revalveable, they offer precise independent compression adjustment for tailoring handling and aggressiveness.

• Compatible with 0–3.5" of front lift (vehicle- and submodel-dependent)
• Vehicle-specific design and valving 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" created by a billet-aluminum manifold increases damping by ~20% to reduce harsh bottom-outs and control high-velocity compression
• Nitrogen-charged monotube with remote reservoir for improved heat dissipation and reduced shock fade
• ICON CDXS compression valves with independent high-speed and low-speed adjustment (10 detented settings each) for precise tuning of handling response and aggressiveness
• Premium-grade 5W shock oil for consistent damping across a wide temperature range
• One-piece linear compression / digressive rebound piston with vehicle-specific valving for refined on- and off-road ride quality
• 7/8" induction-hardened, chrome-plated shock shaft
• Press-in bonded rubber bushing / bar-pin assembly to damp vibration and provide OE-style fitment
• 6061 aircraft-grade aluminum CNC-machined components
• Corrosion-resistant coated steel cylinders for durability and a 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 for extended travel configurations.
• Compatibility varies by submodel: generally compatible with 0–3.5" of front lift on most heavy-duty 2500/3500 submodels; compatible with 0–2" of front lift on certain high-performance 2500 submodels.
