Product Description

ICON 2003-2009 Toyota 4Runner / 2007-2009 Toyota FJ Cruiser 0-3.5" Lift Stage 3 Suspension System (Billet UCA)

The ICON Vehicle Dynamics Stage 3 Suspension System (K53053) is a premium, high-performance suspension upgrade engineered for the 2003–2009 Toyota 4Runner and 2007–2009 Toyota FJ Cruiser. Designed for serious off-road enthusiasts and overland builds, this system builds upon Stage 2 by adding billet aluminum rear lower links for improved articulation, adjustability, and durability. Featuring extended travel 2.5 Series coilovers, billet upper control arms, and a fully balanced rear suspension system, this kit delivers increased wheel travel, superior damping control, and exceptional ride quality across all terrain conditions. 

Adjustable 0–3.5” Front Lift for Maximum Versatility

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 wheel and tire combinations while maintaining optimal drivability both on and off-road. 

2.5 Series Extended Travel Coilovers

The extended travel coilovers significantly increase front suspension droop and overall wheel travel. Paired with vehicle-specific valving, they deliver improved traction, smoother ride quality, and enhanced control in demanding off-road environments. 

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. Featuring ICON’s patented Delta Joint, they combine the durability of a ball joint with the articulation of a uniball while remaining sealed for long-term reliability and quiet operation. 

Billet Rear Lower Links for Strength and Adjustability

A key upgrade in the Stage 3 system is the inclusion of billet aluminum rear lower links. These CNC-machined 6061 aluminum components are significantly stronger than factory links and allow on-vehicle pinion angle adjustment. Designed with integrated skid protection and optimized roll steer geometry, they improve both durability and handling performance.

Rear Coil Springs and 2.0 Aluminum Series Shocks

The rear suspension includes 2” lift coil springs and ICON 2.0 Aluminum Series internal reservoir shocks, tuned specifically for the platform. This ensures balanced damping performance, improved ride comfort, and enhanced control under varying loads and terrain conditions.

Engineered for Maximum Travel and Bolt-On Installation

This system is designed to maximize suspension travel while maintaining proper geometry and long-term reliability. Featuring fully rebuildable shock components and a true bolt-on design, it installs without cutting or welding while delivering a major performance upgrade.
