ICON 0-3.5″ Stage 1 Lift Kit for 2003-2009 Lexus GX470

ICON 2003–2009 Lexus GX470 0-3.5 inches Lift Stage 1 Suspension System

Part Number: K53171

Summary: The ICON Stage 1 Suspension System for the 2003–2009 Lexus GX470 is engineered to provide 0-3.5 inches of adjustable front lift height, allowing for increased ground clearance and larger tire fitment. This system features vehicle-specific tuned 2.5 Series front coilovers and 2.0 Aluminum Series rear shocks to significantly improve damping and ride quality over stock configurations. A critical differentiator for this kit is the included rear coil spring conversion, which replaces the failure-prone factory air bag system with high-performance ICON 2 inches lift coil springs for consistent off-road reliability.

Features

• ICON 2.5 Series Coilovers: 2.5” diameter internal reservoir shocks provide exceptional cooling and increased oil volume to ensure consistent damping performance during aggressive use.
• Rear Coil Conversion: Included conversion hardware replaces factory air bags with ICON 2 inches lift coil springs to provide a reliable mechanical spring rate and improved articulation.
• 6061 CNC Components: Aircraft-grade aluminum machined components provide high strength-to-weight ratios to ensure long-term structural integrity.
• System Durability: CAD plated shock bodies with 7/8 inches front shafts and 5/8 inches rear shafts provide superior corrosion resistance to ensure protection against harsh environmental elements.
• Installation: 100% Bolt-on design provides a direct fitment to ensure a straightforward installation process without the need for cutting or welding.
