ICON Stage 7 Suspension System for 2003-2009 Lexus GX470 with Tubular UCA, 0-3.5" Lift

The ICON Vehicle Dynamics Stage 7 Suspension System is a complete bolt-on lift and performance upgrade for 2003–2009 Lexus GX470 trucks, raising ride height 0–3.5 inches over stock with vehicle-specific-tuned 2.5-inch front coilovers, tubular Delta Joint upper control arms, and a full complement of rear components including remote reservoir shocks, 2-inch lift coil springs, tubular trailing arms, an adjustable track bar, and a rear coil spring conversion kit that eliminates the factory air bag system.

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.

Extended Travel With Geometry You Can Dial In

The front 2.5-inch coilovers pair extended wheel travel with height adjustability across the full 0–3.5-inch lift range, so GX470 owners can run factory wheels and tires or step up to 33-inch rubber without a separate spring swap. Tubular steel Delta Joint upper control arms replace the OE units and correct suspension geometry at lifted heights, giving the front axle more precise alignment and reducing bind through the full range of travel. The Delta Joint combines the weather resistance of a conventional ball joint (zinc-plated housing, grease seal, greaseable design) with the high-angle articulation of a uniball, and is protected under U.S. Patent 10,731,700.

Rear Balance Through Purpose-Built Components

The rear of the Stage 7 system matches the front's capability rather than leaving it as a bottleneck. ICON's 2.5 Aluminum Series remote reservoir rear shocks use one-piece impact-extruded aluminum cylinders for corrosion resistance, and vehicle-specific valving keeps damping matched to the GX470's weight and geometry. Tubular steel upper and lower trailing arms replace the OE links with multi-durometer bushings and pinion-angle adjustability, and the lower links are designed to maintain correct roll-steer geometry on and off road. The included rear coil spring conversion kit removes the factory air bag system entirely, eliminating a common failure point on high-mileage GX470s.

CDC Valves and KDSS Compatibility Built In

Compression Damping Control (CDC) valves are installed in both front and rear shocks and allow the driver to adjust compression damping without tools, tuning ride quality for highway loads, off-road terrain, or a heavily equipped vehicle. The adjustable rear track bar corrects rear axle alignment at lifted heights and supports KDSS-equipped GX470s. KDSS vehicles require rear track bar part 54200, which is included in this kit; front sway bar relocation brackets included in the kit are not used on KDSS-equipped trucks. A 700 lb front coil spring is available separately for heavier-equipped builds.

Features

• 2.5" Front Coilovers with Remote Reservoirs: vehicle-specific tuning, extended travel, CDC valve compression adjustment, CAD-plated bodies with 7/8" shafts
• Tubular Delta Joint UCAs: patented high-angle ball joint (U.S. Pat. 10,731,700), zinc-plated housing, greaseable, corrects geometry at lift
• 2.5 Aluminum Series Rear Shocks: remote reservoirs, one-piece extruded aluminum cylinders, CDC valves, vehicle-specific valving
• Tubular Rear Trailing Arms: upper and lower, multi-durometer bushings, pinion-angle adjustable, correct roll-steer geometry
• Adjustable Rear Track Bar: corrects rear axle alignment, KDSS compatible (KDSS vehicles require part 54200)
• Rear Coil Spring Conversion Kit: eliminates factory rear air bag system; 2" lift rear coil springs included

Specifications

Who This Is For and Isn't

The Stage 7 system suits 2003–2009 Lexus GX470 owners who want a complete, bolt-on suspension upgrade, from daily-driven trucks that need better geometry and ride quality at a modest lift to overlanding builds running 33-inch tires on and off road. KDSS-equipped GX470s are supported with the included adjustable track bar (part 54200 required for KDSS vehicles).

This system does not fit any Lexus GX generation other than the 2003–2009 GX470, and it does not fit Toyota 4Runner, FJ Cruiser, or Land Cruiser models even though some component part numbers overlap with those platforms. Tires larger than 33 inches may fit but will require fender trimming and additional modifications not included in this kit. Remote reservoir mounting brackets may interfere with certain aftermarket bumper mounts and windshield washer bottles; verify clearance before installing an aftermarket front bumper.

Common Questions

Does the Stage 7 system work with the GX470's KDSS (Kinetic Dynamic Suspension System)?

The ICON Stage 7 kit for the 2003–2009 Lexus GX470 is compatible with KDSS-equipped trucks. KDSS vehicles require rear track bar part 54200, which is included in this system. Front sway bar relocation brackets included in the kit are not used on KDSS-equipped vehicles. Certain model years may also require trimming for front reservoir bracket fitment.

What tire size fits without cutting the fenders?

ICON's application data for this Stage 7 system states that 33x11.50-inch tires fit with factory fenders at the 0–3.5-inch lift range this kit provides. Larger tires may fit but will require fender trimming and additional modifications; no specific larger size is guaranteed to clear without those changes.

Can compression damping be adjusted after installation, and does it require tools?

Both the front coilovers and the rear 2.5 Aluminum Series shocks in this Stage 7 system include CDC (Compression Damping Control) valves, which allow the driver to change compression damping settings without tools. This lets the GX470 owner tune ride quality for different terrain types or cargo loads without removing the shocks.

Does this kit eliminate the factory rear air suspension?

Yes. The Stage 7 system for the 2003–2009 Lexus GX470 includes a rear coil spring conversion kit specifically designed to replace the factory rear air bag system with conventional coil springs. The 2-inch lift rear coil springs and rear shocks included in the kit are matched to the converted setup.

Is cutting or welding required to install this system?

The ICON Stage 7 system for the 2003–2009 Lexus GX470 is a bolt-on kit; no cutting or welding is required for installation. Note that remote reservoir mounting brackets may interfere with certain aftermarket bumper mounts or windshield washer bottles, which may require repositioning those components.
