ICON 2003-09 Lexus GX470, 0-3.5" Lift, Stage 7 Suspension System, Tubular UCA (K53177T)
The ICON Vehicle Dynamics Stage 7 Suspension System is a comprehensive performance upgrade engineered for 2003–2009 Lexus GX470 models. Designed to dramatically improve ride quality, suspension articulation, and off-road capability, this system features extended-travel 2.5 Series coilovers with remote reservoirs, tubular upper control arms, heavy-duty rear links, and CDC Valve-adjustable shocks. With increased wheel travel and geometry-correcting components, this system delivers outstanding control, durability, and comfort for both daily driving and demanding off-road use.
Adjustable 0–3.5” Front Lift for Increased Capability
ICON 2.5 Series extended-travel coilovers provide adjustable lift from 0” to 3.5” over stock, allowing installation of larger tires while improving ground clearance and suspension articulation. This adjustability helps maintain proper alignment geometry and enhances overall vehicle performance.
2.5 Series Coilovers with Remote Reservoirs
The front coilovers feature remote reservoirs that increase oil capacity and improve heat dissipation, maintaining consistent damping performance during demanding driving conditions. These shocks are vehicle-specific tuned to maximize ride comfort and off-road stability.
Tubular Upper Control Arms with Delta Joint
This system includes tubular steel upper control arms equipped with ICON’s patented Delta Joint technology. The Delta Joint combines the durability of a ball joint with the articulation of a uniball, improving suspension geometry while enhancing long-term durability and performance.
CDC Valve Technology for Adjustable Damping
Compression Damping Control (CDC) Valves are included in both front and rear shocks, allowing quick compression adjustment to fine-tune ride characteristics based on terrain, cargo load, or driving style. This flexibility improves ride comfort and control across a wide range of conditions.
Rear Coil Conversion Kit Eliminates Factory Air System
This Stage 7 system includes a rear coil spring conversion kit designed to replace the factory rear air suspension system found on GX470 models. The included 2” rear coil springs provide improved reliability, consistent ride height, and enhanced load-carrying capability.
Heavy-Duty Rear Links for Strength and Adjustability
Tubular rear upper and lower links provide increased strength over factory components while allowing pinion angle adjustment. These upgraded links improve articulation and ensure proper drivetrain alignment under increased suspension travel.
Adjustable Rear Track Bar for Proper Axle Alignment
An adjustable rear track bar is included to re-center the rear axle after lift installation and ensure compatibility with KDSS-equipped vehicles. This feature helps maintain correct suspension geometry and predictable handling performance.
Balanced Rear Shock and Spring Performance
The system includes 2” rear coil springs paired with 2.5 Aluminum Series remote reservoir rear shocks. This combination balances the front suspension setup and delivers improved ride comfort, load support, and off-road performance.
