ICON 4.5″ Lift Kit Stage 4 for 2007-2018 Jeep Wrangler (JK/JKU)

ICON 2007–2018 Jeep JK Wrangler 4.5 inches Lift Stage 4 Suspension System

Part Number: K24004

Summary: The ICON Stage 4 suspension system for the 2007–2018 Jeep Wrangler JK is a comprehensive performance solution engineered to provide 4.5 inches of lift while balancing wheel travel, articulation, and precise handling. This system features ICON’s dual-rate coil springs and 2.5 Aluminum Series Reservoir shocks equipped with CDCV (Compression Damping Control Valve) for ultimate user tunability. Designed as a complete engineering solution rather than a simple lift kit, this stage includes adjustable track bars and a high-steer flip kit to optimize steering geometry and axle positioning for both trail crawling and high-speed desert transit.

Features

• Dual-Rate Coil Springs: Front and rear dual-rate springs provide a soft initial rate for on-road comfort and a firmer secondary rate to prevent bottoming out to ensure they never sag.
• CDCV Technology: The Compression Damping Control Valve provides 10 levels of user-adjustable damping force to ensure optimized ride quality across varying terrains and vehicle loads.
• High-Steer Flip Kit: A high-steer taper adapter and drag link flip provide proper steering geometry without a drop pitman arm to ensure increased ground clearance and reduced bump steer.
• Adjustable Track Bars: On-vehicle adjustable front and rear track bars provide precise axle centering to ensure optimal tracking and alignment.
• Multi-Link Articulation: Links utilizing dual-rate bushings and PTFE-lined rod ends provide tuned vibration isolation and controlled deflection to ensure maximum articulation and responsiveness.
• System Durability: 2.5 Aluminum Series shocks and stainless steel hardware provide superior heat dissipation and corrosion resistance to ensure long-term performance in harsh environments.
• Installation: 100% bolt-on design provides a straightforward upgrade path to ensure the vehicle can be returned to stock if necessary.
