ICON Stage 1 suspension for the 2024 Lexus GX550 uses vehicle‑specific tuned 2.5 Series coilovers with internal reservoirs and ICON springs to increase wheel travel and damping for improved control and ride quality. Adjustable front lift of 1.25–3" and 2" rear lift yield a level stance and room for larger tires. Differential drops and polyurethane bushings help maximize travel and limit differential movement under load.
