Not sure what you need?
For Lexus GX550 owners who expect more from every drive, ReadyLIFT introduces the 3" SST3.3 Premium Suspension System. Designed specifically for the 2024–2025 Lexus GX550, this system enhances capability and road presence while preserving the composed ride quality and premium feel that define the Lexus experience.
At the heart of the SST3.3 system are Falcon 3.3 Fast Adjust shocks, delivering effortless tuning to match the moment, whether that’s smooth highway cruising, winding backroads, or confident off-pavement exploration. Precision-engineered suspension geometry, heavy-duty DOM tubular upper control arms, and a thoughtfully balanced lift work together to improve clearance, maintain confident handling, and create a stance that looks as purposeful as it performs.
This is not about going extreme; it’s about elevating what your GX550 already does exceptionally well.
Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.
Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
