ICON Stage 1 Suspension System for 2003-2009 Lexus GX470, 0-3.5" Lift

The ICON Vehicle Dynamics Stage 1 Suspension System is a complete front-and-rear upgrade for the 2003–2009 Lexus GX470, delivering 0–3.5 inches of adjustable lift height through a matched set of 2.5 Series front coilovers, 2.0 Aluminum Series rear shocks, ICON-engineered rear coil springs, and a rear coil conversion kit that eliminates the factory air-bag system. The kit ships as a bolt-on system requiring no cutting or welding.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Adjustable Lift Without Compromise

The 2.5 Series front coilovers are height-adjustable across the full 0–3.5 inch lift range, so the GX470 can run factory wheels and tires or step up to the recommended 33×11.50 inch aftermarket tire without a fixed-height commitment. Coilover height figures are calibrated for a stock-equipped vehicle; heavier builds can specify the available 700 lb front coil spring to suit added weight.

Vehicle-Specific Valving Front and Rear

Both the 2.5 Series front coilovers and the 2.0 Aluminum Series rear shocks use vehicle-specific valving tuned for the GX470's weight and suspension geometry. Internal reservoirs on both front and rear shocks extend fade resistance during repeated off-road cycles. The 2.0 Series rear shocks use 5/8 inch shafts; the front coilovers use 7/8 inch shafts with FK rod-end bearings to reduce deflection over time.

Factory Air-Bag Elimination Included

The GX470's factory rear air-bag suspension is replaced by the included rear coil conversion kit (part 56110), paired with ICON's 2-inch lift rear coil springs. Removing the air system eliminates a common long-term failure point and simplifies future suspension service. All coilover shock bodies are CAD-plated for corrosion resistance, and CNC-machined 6061 aircraft-grade aluminum components are used throughout.

Specifications

Who This Is For and Isn't

This system suits 2003–2009 Lexus GX470 owners who want a complete, bolt-on suspension upgrade with adjustable lift from 0 to 3.5 inches, improved off-road damping, and elimination of the factory rear air-bag system. It is compatible with both KDSS and non-KDSS equipped vehicles.

This system does not fit any Lexus GX460 or any model year outside 2003–2009. KDSS-equipped vehicles require the separately sold rear track bar (part 54200). Remote reservoir mounting brackets may interfere with certain aftermarket bumper mounts and windshield washer bottles; verify clearance before installing an aftermarket bumper. Tires larger than 33×11.50 inches may require fender trimming. This kit does not include wheels, tires, or alignment services.

Common Questions

Does this system work with the GX470's factory KDSS (Kinetic Dynamic Suspension System)?

The ICON Stage 1 system for the 2003–2009 Lexus GX470 is compatible with KDSS-equipped vehicles. On KDSS builds, the front sway bar relocation brackets included in the kit are not used. KDSS-equipped vehicles also require the separately sold ICON rear track bar, part number 54200, to complete the installation.

Will my factory wheels and tires still fit after installing this system?

The ICON Stage 1 system for the GX470 is confirmed compatible with factory wheels and tires at all lift settings within the 0–3.5 inch range. For aftermarket fitments, ICON recommends 33×11.50 inch tires; tires larger than that may require fender trimming or other modifications.

What does the rear coil conversion kit do, and is it required?

The GX470 uses a factory rear air-bag suspension system. The included rear coil conversion kit (part 56110) replaces that air system with conventional coil springs, which are paired with the kit's 2.0 Aluminum Series rear shocks. The conversion kit is specific to the GX470 platform and is included in this Stage 1 system, with no separate purchase needed.

Can the lift height be adjusted after installation?

The 2.5 Series front coilovers in this Stage 1 system are height-adjustable across the full 0–3.5 inch lift range after installation. Lift height figures are based on a stock-equipped vehicle; actual ride height will vary with added accessories or cargo weight. A 700 lb front coil spring is available separately for heavier-equipped GX470 builds.

Is cutting or welding required to install this system?

No cutting or welding is required to install the ICON Stage 1 Suspension System on a 2003–2009 Lexus GX470. The system is designed as a bolt-on upgrade. Note that certain model years may require trimming for front reservoir bracket fitment; confirm applicability for your specific year before installation.
