ICON Vehicle Dynamics 2019–2026 Chevrolet Silverado 1500 / GMC Sierra 1500 Stage 4 Suspension System

The ICON Vehicle Dynamics Stage 4 suspension for 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 is engineered to dramatically improve on- and off-road ride quality by increasing wheel travel and damping performance. The system uses ICON 2.5 Series remote reservoir coilovers up front and 2.5 Series piggyback rear shocks for superior cooling and consistent damping. Coilovers feature ICON-engineered springs and height adjustability to allow larger tire fitment and improved vehicle control. Billet 6061 aluminum upper control arms with ICON’s patented Delta Joint deliver enhanced articulation, durability, and corrosion resistance for daily-driven use.

• Adjustable front coilovers: 1.5"–3.5" of lift height for larger wheel and tire combinations
• Improved travel: Up to 35% increase in front wheel travel over stock
• 2.5 Series shocks: CAD-plated shock bodies with 7/8" shafts and corrosion-resistant construction
• Aluminum rear shocks: One-piece impact-extruded cylinders for corrosion resistance and consistent finish
• Remote reservoirs: 7.5" aluminum reservoirs for increased oil and nitrogen volume and cooler operating temperatures
• End-user tuning: Easy-to-adjust CDC (Compression Damping Control) for compression adjustment by terrain and load
• Durable hardware: FK rod end bearings for extended longevity and minimal deflection; shocks are fully rebuildable and revalvable
• Upper control arms: CNC-machined 6061 billet aluminum arms with on-vehicle camber and caster adjustment and added wheel travel when paired with extended-travel coilovers
• Patented Delta Joint: Zinc-plated, greaseable design combining ball-joint weather resistance with uniball angularity for noise-free operation
• Direct bolt-in: Designed for straightforward installation
• Warranty: Lifetime guarantee against ICON fabricated component breakage or manufacturer defect
