ICON Stage 2 Suspension System for 2003-2009 Lexus GX470 with Tubular UCA

The ICON Stage 2 Suspension System for the 2003–2009 Lexus GX470 delivers 0–3.5 inches of adjustable lift with extended front wheel travel and a rear coil conversion that eliminates the factory air bag system, all as a bolt-on kit requiring no cutting or welding. The system ships as five component assemblies covering front coilovers, tubular upper control arms, rear coil springs, rear shocks, and the rear coil conversion kit.

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 Up Front, Balanced Performance Out Back

The front of the Stage 2 system uses 2.5-inch internal-reservoir coilover shocks tuned specifically for the GX470's weight and geometry. Extended travel means the front suspension can articulate further before topping out, which translates directly to better wheel contact on uneven terrain and a more composed ride on washboard roads. Height adjustment across the full 0–3.5-inch range lets owners dial in stance without swapping springs.

At the rear, ICON 2-inch lift coil springs pair with 2.0 Aluminum Series internal-reservoir shocks using vehicle-specific valving. The included rear coil conversion kit replaces the factory air bag system with a conventional coil setup, removing a component that can become a maintenance liability on older GX470s and simplifying the rear suspension for long-term reliability.

Delta Joint Upper Control Arms: Durability Without the Uniball Trade-Off

The tubular steel upper control arms use ICON's patented Delta Joint (U.S. Pat. 10,731,700) in place of a conventional uniball. A zinc-plated housing and grease seal protect the joint from moisture and debris, addressing the primary failure mode of an exposed uniball on a daily-driven or trail vehicle. Metal-on-metal construction with a greaseable design supports long service life, while the joint's high-angle capability preserves the articulation benefit that makes a uniball desirable in the first place. The result is a control arm that corrects suspension geometry for more predictable alignment and handling without sacrificing serviceability.

• Tubular UCA with Delta Joint: patented high-angle ball joint with zinc-plated housing and grease seal (U.S. Pat. 10,731,700)
• 0–3.5" adjustable lift: coilover height adjustment accommodates factory wheels and tires through recommended aftermarket sizing
• Rear coil conversion kit included: eliminates factory rear air bag system
• 2.0 Aluminum Series rear shocks: internal reservoir, 5/8" shafts, vehicle-specific valving
• Bolt-on installation: no cutting or welding required; all shocks are fully serviceable

Specifications

Who This Is For and Isn't

This system suits 2003–2009 Lexus GX470 owners seeking 0–3.5 inches of lift with improved front wheel travel, corrected suspension geometry, and a conventional rear coil setup in place of the factory air bag system, whether for overlanding, trail use, or a more capable daily driver. The system is compatible with KDSS-equipped GX470s (front sway bar relocation brackets are not used on KDSS vehicles).

This system does not fit any Lexus GX460, GX550, or any non-GX470 vehicle. KDSS-equipped vehicles require the separate rear track bar (ICON part 54200), which is not included. Remote reservoir mounting brackets may interfere with aftermarket bumper mounts and windshield washer bottles. Certain model years require trimming for front reservoir bracket fitment. Lift heights indicated are for a stock-equipped vehicle; a 700 lb front coil spring is available separately for heavier-equipped builds.

Common Questions

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

The ICON Stage 2 system for the 2003–2009 Lexus GX470 is compatible with KDSS-equipped vehicles. On KDSS GX470s, the front sway bar relocation brackets included in the kit are not used. KDSS-equipped vehicles also require the ICON rear track bar (part 54200), which is sold separately and not included in this system.

What happens to the factory rear air bag suspension?

The Stage 2 system includes a rear coil conversion kit (ICON part 56110) specifically for the GX470 platform. This kit replaces the factory rear air bag system with a conventional coil spring setup, eliminating the air bags entirely. The rear 2-inch lift coil springs and 2.0 Aluminum Series shocks then provide the rear suspension function.

What wheel and tire sizes does this lift support?

The ICON Stage 2 system for the GX470 is confirmed to work with factory wheels and tires. ICON recommends aftermarket wheels in 17x8.5-inch (4.75-inch backspace / 0mm offset), 18x9-inch (5.00-inch backspace / 0mm offset), or 20x9-inch (5.00-inch backspace / 0mm offset) sizing. The recommended aftermarket tire size is 33x11.50 inches; larger tires may fit but fender trimming and other modifications may be required.

Is cutting or welding required to install this system?

The ICON Stage 2 Suspension System for the 2003–2009 Lexus GX470 is a bolt-on system. No cutting or welding is required for installation. Note that certain model years may require trimming for front reservoir bracket fitment, and remote reservoir mounting brackets may interfere with aftermarket bumper mounts or windshield washer bottles depending on the specific vehicle configuration.

Are the shocks serviceable after installation?

All shocks included in the ICON Stage 2 system for the GX470 are fully serviceable. The front 2.5-inch coilovers feature a CAD-plated shock body with 7/8-inch shafts and FK rod end bearings. The rear 2.0 Aluminum Series shocks use 5/8-inch shafts with internal reservoirs, and both front and rear units can be rebuilt rather than replaced when service is needed.
