Q. What jack size is required to lift a car?

Answer

Lifting an SUV or 4x4 will require a heavier-duty jack, rated at 3 tons. A two-ton jack is enough for most maintenance tasks, but it's always smart to upgrade if possible. Towing capability of the chosen jack should be at least 75% of the vehicle's total weight. Stickers placed in the door jam on the driver's side often display the vehicle's maximum allowable load. All needs is a jack that can raise at least 3 tons (or 6,000 pounds) and has a minimum lifting height of 16 inches, and anyone is going good to go. There are jacks that are only a few inches high and can be rolled easily under the vehicle.
