Product Description

ICON 2003-2009 Lexus GX470 0-3.5" Lift Stage 3 Suspension System (Billet UCA)

The ICON Vehicle Dynamics Stage 3 Suspension System (K53173) is a premium, fully engineered suspension upgrade for the 2003–2009 Lexus GX470. Designed for serious off-road enthusiasts and overland builds, this system builds upon the Stage 2 package by adding billet aluminum rear lower links and an adjustable rear track bar. The result is a complete suspension solution that significantly increases wheel travel, improves articulation, and enhances both on-road stability and off-road performance. 

Adjustable 0–3.5” Front Lift for Custom Stance

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 flexibility supports larger, more aggressive wheel and tire setups while maintaining excellent drivability and control. 

2.5 Series Extended Travel Coilovers with Internal Reservoirs

The front coilovers feature extended travel design with internal reservoirs to improve heat dissipation and maintain consistent damping performance under demanding conditions. This setup increases front wheel travel and enhances traction and control across rough terrain. 

Billet Aluminum Upper Control Arms with Delta Joint

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

Billet Aluminum Rear Lower Links for Strength and Geometry Correction

A key upgrade in the Stage 3 system is the inclusion of billet aluminum rear lower links. These heavy-duty links improve articulation, allow on-vehicle pinion angle adjustment, and enhance roll-steer geometry for improved handling both on and off-road. 

Rear Coil Springs and 2.0 Aluminum Series Shocks

The rear suspension includes 2” lift coil springs paired with ICON 2.0 Aluminum Series internal reservoir shocks. This combination delivers balanced damping performance, improved ride comfort, and enhanced stability under load or off-road conditions. 

Adjustable Rear Track Bar for Proper Axle Alignment

An adjustable rear track bar is included to correct axle shift after lifting and restore proper rear-end geometry. This ensures predictable handling, improved stability, and proper tire alignment on and off-road. 

Engineered for Maximum Travel and Durability

This system is designed to maximize usable suspension travel while maintaining factory-like drivability. High-strength materials, fully rebuildable shocks, and precision engineering ensure long-term durability in demanding environments. 

Bolt-On Installation with OEM Fitment

The Stage 3 system is a fully bolt-on upgrade that utilizes factory mounting points with no cutting or welding required. This makes installation straightforward while delivering a significant improvement in suspension capability.
