What is the purpose of the ICON Delta Joint PRO in the upper control arms?

The Delta Joint PRO is a serviceable and rebuildable ball joint replacement that allows for full bump and droop travel of the front suspension. It also eliminates binding, improving overall suspension performance and component longevity.

How does the dual-rate rear coil spring design benefit my GX550?

The dual-rate design offers a softer spring rate for normal ride height, contributing to on-road comfort. It also has a firmer overload rate that provides excellent bottoming resistance, especially beneficial during off-road driving or when carrying extra weight.

What is included in the Stage 3 suspension system?

The Stage 3 system includes tubular upper control arms with Delta Joint PRO, adjustable 2.5 Series front coilovers, dual-rate rear coil springs, 2.0 Aluminum Series internal reservoir rear shocks, an adjustable rear track bar, front differential drop brackets, and differential mounting bushings.

About this part

Product Details

ICON Vehicle Dynamics is known for making tough suspension components that perform well both on the pavement and when you head off-road. This Stage 3 system is built specifically for your 2024 Lexus GX550, giving it the ability to handle more demanding terrain while still offering a comfortable ride on your daily commute. It's designed to increase wheel travel and improve damping, which means better control and a smoother experience no matter where you're driving.

This kit includes tubular upper control arms (UCAs) that correct your front-end geometry and add caster, along with improved clearance for suspension parts. The UCAs use ICON's patented Delta Joint PRO, which is serviceable and rebuildable, allowing for full suspension travel without binding. The front coilovers are height-adjustable from 1.25 to 3 inches, letting you fit larger tires, and they feature internal reservoirs for better cooling. You also get dual-rate rear coil springs for a good balance of on-road comfort and off-road bottoming resistance, plus a 2-inch rear lift to level the stance. The adjustable rear track bar helps keep your rear axle centered, and the ICON 2.0 Aluminum Series rear shocks are tuned specifically for your GX550.

To further enhance performance and prevent binding, the system includes front differential drop brackets and polyurethane differential mounting bushings. Many of the components are CNC machined from 6061 aircraft-grade aluminum for strength and light weight, and the shock bodies are CAD plated for corrosion resistance. This system is a solid choice if you're looking to significantly improve your GX550's capabilities on and off the road.
