ICON V.S. 2.5 Aluminum Series Shocks

ICON V.S. 2.5 Aluminum Series shocks are vehicle-specific monotube shocks with remote reservoirs, engineered to deliver outstanding off-road performance while maintaining a comfortable street ride. Each shock is configured for its application in both length and damping tune and is fully rebuildable and revalveable. An internal billet-aluminum manifold creates an internal Bump Zone that increases damping near full compression to help prevent harsh bottoming. ICON’s Compression Damping Control Valve (CDCV) provides precise, high-resolution compression adjustment for a wide range of driving conditions.

• Fitment: Compatible with 0-3.5" of front lift over stock (vehicle-specific).
• Extended travel: Extended travel length requires aftermarket front upper control arms and provides maximum wheel travel.
• Internal Bump Zone: Increases damping by approximately 20% to improve control at high-velocity compression and reduce harsh bottom outs.
• Nitrogen-charged monotube with remote reservoir: Improves heat dissipation and reduces shock fade during prolonged use.
• CDCV technology: Offers 10 levels of high-resolution compression adjustability via an external knob.
• Premium internals: Uses premium grade 5WT shock oil and a one-piece digressive piston design with vehicle-specific valving for consistent damping across temperatures.
• Durable construction: 7/8" induction-hardened, chrome-plated shock shaft; 6061 aircraft-grade CNC-machined aluminum components; one-piece hard-anodized, impact-extruded aluminum cylinders for corrosion resistance.
• OE-style fitment: Press-in, bonded rubber bushing/bar pin assembly damps road vibration and provides factory-type fitment.
• Serviceable: 100% rebuildable and 100% revalveable for long-term maintenance and tuning.

Technical Notes

• These systems are to be used with aftermarket upper control arms only.
• Shocks are fully serviceable. Lift heights indicated are for a stock-equipped vehicle.
• Compatibility varies by vehicle submodel: compatible with up to 0-3.5" of front lift on most 3/4-ton heavy-duty pickup submodels; compatible with up to 0-2" of front lift on certain high-performance or specialized submodels. Confirm vehicle-specific fitment before purchase.
