For Lexus GX550 owners who expect more from every drive, ReadyLIFT introduces the 3" SST3.3 Premium Suspension System.
Designed specifically for the 2024–2026 Lexus GX550, this complete front and rear suspension system enhances ground clearance, capability, and road presence while preserving the composed ride quality and premium feel that define the Lexus driving experience.
At the heart of the system are Falcon 3.3 Fast Adjust remote-reservoir dampers. Three unique base-valve positions and eight micro-adjustment positions provide extensive suspension tuning for smooth highway cruising, winding roads, towing, and confident off-pavement exploration.
Heavy-duty DOM tubular upper control arms help maintain proper suspension geometry and ball-joint operating angles, while the carefully balanced 3" front and 2" rear lift creates a purposeful, neutral stance.
For GX550 owners who value luxury, control, and the freedom to explore beyond the pavement, the ReadyLIFT SST3.3 delivers added capability without compromising the character of the vehicle.
