Product Description

ICON 2003-2009 Lexus GX470 0-3.5" Lift Stage 2 Suspension System (Billet UCA)

The ICON Vehicle Dynamics Stage 2 Suspension System (K53172) is a premium performance upgrade engineered for the 2003–2009 Lexus GX470. Designed to significantly increase wheel travel, improve damping control, and enhance overall ride quality, this system builds upon Stage 1 by adding extended travel coilovers and billet aluminum upper control arms. Ideal for both daily driving and serious off-road use, this system delivers a balanced combination of comfort, durability, and precision handling. 

Adjustable 0–3.5” Front Lift for Versatile Performance

ICON 2.5 Series extended travel coilovers provide adjustable lift from 0 to 3.5 inches, allowing precise tuning for ride height, tire clearance, and suspension geometry. This adjustability supports larger wheel and tire combinations while maintaining excellent on-road drivability.

2.5 Series Extended Travel Coilovers with Internal Reservoirs

The front suspension features extended travel coilovers with internal reservoirs to improve heat dissipation and maintain consistent damping performance under demanding conditions. This setup increases front wheel travel and enhances off-road capability. 

Billet Aluminum Upper Control Arms with Delta Joint

CNC-machined billet aluminum upper control arms are included to correct suspension geometry and allow proper alignment at increased lift heights. Equipped with ICON’s patented Delta Joint, they provide high articulation, reduced bind, and improved durability compared to traditional ball joints or uniballs. 

Rear Coil Springs and 2.0 Aluminum Series Shocks

The rear suspension is upgraded with ICON 2” lift coil springs and 2.0 Aluminum Series internal reservoir shocks, tuned specifically for the GX470 platform. This combination ensures balanced damping performance, improved ride comfort, and enhanced control in both on-road and off-road environments. 

Optimized Suspension Geometry and Ride Quality

This system is engineered to maintain proper suspension geometry while maximizing wheel travel and ride comfort. The combination of extended travel coilovers and upgraded control arms ensures improved handling characteristics and long-term reliability. 

Fully Bolt-On Installation

The Stage 2 system is designed as a complete bolt-on upgrade utilizing factory mounting points. No cutting or welding is required, making installation straightforward while delivering a significant improvement in suspension performance.
