What Size Aluminum Floor Jack Do You Need?
For most cars, crossovers and SUVs, a 2 ton to 3 ton aluminum floor jack is the right size, because the rating only needs to exceed the part of the vehicle you lift. Choose the capacity first, then make sure the jack fits under your car and reaches high enough to lift it. Use jack stands for any work under the vehicle.

A floor jack never lifts your whole vehicle at once. When you raise one end or one corner, the jack carries only part of the total weight. Still, the rating should comfortably exceed the load you plan to raise, so a margin matters.
A common rule of thumb is to pick a jack rated for at least half of your vehicle's gross weight, and more is better. Your owner's manual lists the weight, so check it before you shop. Heavier trucks and full-size SUVs usually call for the higher end of the range.
On our best aluminum floor jack page, five of the seven jacks are rated 3 ton, one is 2 ton and one is 1.5 ton. That spread covers most home garages. If you want to see those capacities side by side, our best aluminum floor jack comparison puts them on one spec sheet.
Match the jack to your vehicle type
Capacity is a starting point, and vehicle type helps you narrow it down. These are general guidelines, so always confirm against your own vehicle's weight.
- Small cars and sports cars: a 1.5 ton or 2 ton jack can handle the load, but low ground clearance often matters more than capacity.
- Sedans and crossovers: a 2 ton or 3 ton jack gives a comfortable margin.
- SUVs and light trucks: a 3 ton jack is the safer choice, since these vehicles weigh more and sit higher.
- Mixed household: if you service more than one vehicle, size the jack for the heaviest one.
Check minimum saddle height before you buy
Minimum saddle height is how far the pad sits above the floor when the jack is fully lowered. If the jack cannot slide under your lift point, the capacity does not matter.
The jacks on our page start between 3 in and 3.75 in. The JEGS 3-ton model has the lowest start at 3 in. Three jacks, the SATA 3-ton, the YELLOW JACKET 3-ton and the ARCAN A20019, start at 3.75 in. If your car sits very low, even a fraction of an inch can decide whether it fits.
Measure the gap between the ground and your lift point, then compare it to the jack's starting height. Our best low profile floor jack page is a good next stop if clearance is your main concern.
Check the lift range for taller vehicles
The other end of the range matters too. Maximum height must reach your lift point, with enough room to place stands afterward. A tall SUV or truck needs more reach than a sedan.
Our page lists maximum heights from 14 in on the 1.5 ton ARCAN A20006 up to 19.88 in on the 2 ton ARCAN A20017. The 3-ton models run from 18 in to 19.125 in. That 14 in ceiling is fine for some cars, but it limits which vehicles the smaller jack suits.
Compare the real specs side by side
Here are the published figures from the jacks on our page. A dash means the listing does not publish that number.
Aluminum is chosen to save weight, but the numbers vary, so check the listed weight rather than assuming.
| Jack | Capacity | Height range (in) | Weight (lb) | Length x width (in) |
|---|---|---|---|---|
| SATA 3T Aluminum | 3 ton | 3.75 to 19.125 | Not listed | 28.35 x 13.58 |
| YELLOW JACKET 3T | 3 ton | 3.75 to 18.9 | 57.8 | 25.6 x 12.6 |
| ARCAN A20019 | 3 ton | 3.75 to 18 | 56 | 30 x 13.5 |
| ARCAN A20017 | 2 ton | 3.54 to 19.88 | 46.3 | 29.53 x 13 |
| JEGS 555-80077 | 3 ton | 3 to 19 | 58 | 32 x 16 |
| NOS NSJ0301 | 3 ton | 3.7 to 19.1 | 58 | 26.4 x 13 |
| ARCAN A20006 | 1.5 ton | 3.5 to 14 | 32.8 | Not listed |
Think about weight and storage
The reason to buy aluminum is usually weight. Among the six jacks that list weight, the range runs from 32.8 lb to 58 lb. The 1.5 ton ARCAN is the lightest at 32.8 lb, while among 3-ton models with a listed weight, the ARCAN A20019 is the lightest at 56 lb.
Footprint matters if you store the jack in a tight space or a trunk shelf. The YELLOW JACKET is the shortest at 25.6 in and the narrowest at 12.6 in among the jacks that list sizes. The JEGS is the longest at 32 in and the widest at 16 in.

Safety checks that matter more than size
A floor jack is for lifting, not for holding. Never get under a vehicle supported only by a jack. Always place rated jack stands under solid frame points, and lower the vehicle onto them before you work.
Work on flat, hard, level ground and chock the wheels that stay on the floor. Lift only at the lift points your owner's manual shows. Wear safety glasses when working under or around a raised vehicle, since dirt and debris can fall.
Look for safety features when you compare. A dual-piston pump cuts the strokes needed to reach the vehicle. An overload valve limits the load, and a listed standard such as ASME gives you something to verify. Not every jack on our page lists these, so compare each spec row.
Frequently asked questions
Is a 3 ton jack too big for a small car?
No. A higher rating just gives more margin. The bigger concern is whether the jack's minimum height fits under the car and whether the extra weight is manageable for you.
Are aluminum floor jacks as safe as steel ones?
Safety depends on the rating, build quality and how you use it, not on the metal alone. Check for an overload valve and a listed standard, and always support the vehicle with jack stands.
Can a 1.5 ton jack lift a 3 ton vehicle?
It may lift one end, because the jack carries only part of the weight. But the lower rating leaves little margin, and its 14 in maximum height limits the vehicles it reaches. Check your manual before relying on it.
Does a dual-piston pump change the size I need?
No. It changes speed, not capacity. A dual-piston pump raises the saddle with fewer strokes, which is convenient but does not replace checking rating and height.
