Lift Extension Posts: This floor jack is designed for lifting off-road vehicles. It lifts from 5.9–23.2 in (150–590 mm). With the extension post installed, max height reaches 29.3 in (745 mm) for off-road vehicles and other high-clearance vehicles Large-Diameter Casters: The off-road hydraulic floor jack features four large-diameter casters. It rolls smoothly over rough flagstone and gravel roads. Deep tread improves traction, while the base plate helps reduce sinking during outdoor lifting 3T Max Capacity: Our high lift floor jack supports up to 3 tons (6,614 lbs). It lifts off-road vehicles, SUVs, pickups, and trucks. Ideal for tire changes, brake service, suspension work, and other undercarriage work. Use jack stands for long-term support Dual-Piston Quick Lift: This high lift jack uses a dual-piston hydraulic pump system for faster lifting. The twin cylinders distribute weight evenly. A sealed hydraulic system helps reduce leakage and supports stable lifting with lower overload risk Secure & Stable Support: The high lift car jack combines heavy-duty steel and aluminum for strength. The structure helps reduce wobble during lifting. A rotating saddle with a non-slip rubber pad safeguards the underbody and aligns easily with lift points
