ICON 0-3.5″ Stage 5 Lift Kit with Billet UCA for 2003-2009 Lexus GX470

ICON 2003–2009 Lexus GX470 0-3.5 inches Lift Stage 5 Suspension System with Billet UCA

Part Number: K53175

Summary: The ICON Stage 5 suspension system provides a comprehensive performance upgrade for the 2003–2009 Lexus GX470, offering an adjustable front lift height of 0-3.5 inches. This system features 2.5 Series remote reservoir coilovers and rear shocks for superior heat dissipation, paired with CNC-machined Billet Aluminum upper control arms featuring the patented Delta Joint. A critical differentiator for the GX470 platform is the included rear coil spring conversion kit, which replaces the failure-prone factory air bags with high-performance ICON 2 inches lift coil springs and adjustable billet lower links.

Features

• Extended Travel Coilovers: 2.5 inches diameter bodies with remote reservoirs provide increased oil volume for improved heat dissipation and consistent damping during aggressive off-road use.
• Delta Joint Technology: Patented high-angle ball joints combine the durability of a sealed joint with the performance of a uniball to ensure predictable handling and long-term reliability.
• Billet Upper Control Arms: 6061 aircraft-grade aluminum construction provides on-vehicle camber and caster adjustment to ensure precise alignment specs at increased lift heights.
• Billet Lower Links: CNC-machined aluminum trailing arms provide increased strength and on-vehicle pinion angle adjustment to ensure optimum driveline geometry.
• Air-to-Coil Conversion: The included conversion kit eliminates the factory rear air system to ensure maximum reliability and consistent ride height in rugged environments.
• System Durability: CAD-plated shock bodies and FK Rod End bearings provide maximum corrosion resistance to ensure longevity in harsh conditions.
• Installation: A 100% bolt-on design provides a straightforward upgrade path to ensure no cutting or welding is required for installation.
