ICON ICON 2019–2023 GM 1500 Stage 4 1.5–3.5 inches Lift Suspension System

Part Number: K73064

Summary: The ICON Stage 4 suspension system provides 1.5–3.5 inches of lift height for the 2019–2023 Chevrolet Silverado and GMC Sierra 1500, engineered to maximize off-road performance and on-road comfort. This comprehensive system features 2.5 Series Remote Reservoir CDCV coilovers and 2.5 Series Piggyback CDCV rear shocks to ensure peak damping consistency during aggressive use. A primary differentiator is the inclusion of CNC-machined 6061 Billet Aluminum Upper Control Arms equipped with the patented Delta Joint, offering superior suspension geometry and on-vehicle adjustability.

Features

• 2.5 Series CDCV Coilovers: 2.5-inch diameter remote reservoir shocks with CDC Valve technology provide adjustable compression damping to ensure optimized ride quality across varied terrain and cargo loads.
• Delta Joint Technology: The patented Delta Joint combines the durability of a sealed ball joint with the high-angle articulation of a uniball to ensure long-term reliability and maximum wheel travel.
• Billet Upper Control Arms: CNC-machined 6061 billet aluminum construction provides on-vehicle camber and caster adjustment to ensure predictable handling and precise alignment.
• Performance Wheel Travel: Specialized shock valving and extended travel design provide up to a 35% increase in front wheel travel to ensure superior control in technical off-road environments.
• System Durability: CAD-plated shock bodies and impact-extruded aluminum cylinders provide maximum corrosion resistance to ensure component longevity in harsh environments.
• Installation: A 100% direct bolt-in design provides a straightforward mounting process to ensure a secure fitment without major structural modification.

Frequently Asked Questions

Is this system compatible with the Silverado Trail Boss or GMC Sierra AT4?
Yes, however, the lift height range is reduced to 0–1.5 inches over the factory sub-model lift. For a level stance, it is recommended to replace factory rear blocks with 1 inches blocks.

What is the benefit of the CDC Valve (CDCV)?
The Compression Damping Control (CDC) valve allows for 10 distinct user-adjustable settings, enabling you to tune the ride stiffness based on terrain or vehicle load.
