SST 3.3 Suspension Kit with 3 in Front Lift and 2 in Rear Lift for GX 550 (2024–Present)

ReadyLift developed the SST 3.3 Suspension Kit to enhance the capability and presence of the GX 550 while preserving its refined driving characteristics. The system delivers increased clearance, improved suspension control, and premium ride quality across highway, city, and off-road environments.

TeraFlex Falcon 3.3 Fast Adjust shocks feature remote reservoirs with multiple base valve settings and micro-adjustment positions for highly customizable tuning, allowing drivers to tailor ride characteristics for comfort, handling precision, or performance.

Heavy-duty tubular upper control arms and a differential drop kit are engineered to maintain alignment geometry and articulation under lift conditions. The corrected design improves steering feel, wheel control, and long-term suspension durability.

The balanced 3-inch front and 2-inch rear lift configuration improves ground clearance and tire fitment while maintaining composed on-road behavior. Carefully tuned damping preserves the premium driving experience expected from the GX 550 platform.

This kit is engineered as a complete bolt-on package using vehicle-specific mounting locations and precision-fit components. The design supports larger tire configurations while maintaining factory electronic integration and daily-driving comfort.
