A floor jack is one of the most useful pieces of equipment you can have in a home garage—but buying the biggest jack you can find isn’t always the answer.
Capacity, minimum height, maximum lift height, vehicle weight, and the type of vehicle you’re working on all matter.
Here’s what to look for before buying a floor jack.
Understanding Floor Jack Ratings
Floor jacks are usually advertised by their maximum lifting capacity.
Common sizes include:
- 1.5-ton
- 2-ton
- 2.5-ton
- 3-ton
- 3.5-ton
- 4-ton
One ton equals 2,000 pounds, so a 3-ton jack has a rated lifting capacity of 6,000 pounds.
However, that doesn’t mean you should simply look at your vehicle’s total weight and buy a jack with exactly that capacity.
A jack normally lifts one end or corner of the vehicle rather than the entire vehicle at once, but having adequate capacity provides a useful safety margin.
Always stay within the jack manufacturer’s rated capacity.
What Size Jack for a Small Car?
For many compact cars and sedans, a 2-ton jack can provide enough capacity.
But capacity isn’t the only concern.
Many modern cars sit relatively low, so check the jack’s minimum saddle height before buying.
A low-profile jack can be much easier to position underneath low cars.
What Size Jack for an SUV?
For many SUVs and crossovers, a 2.5- or 3-ton floor jack is a more versatile choice.
Larger SUVs can weigh considerably more than small crossovers, so check the actual weight of your specific vehicle rather than assuming they’re all similar.
You’ll also want enough lift height to get the tires off the ground.
What Size Jack for a Half-Ton Pickup?
For trucks such as an F-150, Silverado 1500, Sierra 1500, or Ram 1500, a 3-ton floor jack is a common starting point.
But check the specifications for your particular truck and jack.
Modified trucks, heavy accessories, and certain configurations can change vehicle weight or the amount of lift required.
What About 3/4-Ton and 1-Ton Trucks?
Heavy-duty pickups require more consideration.
Vehicles such as an F-250/F-350, Silverado/Sierra 2500HD or 3500HD, and Ram 2500/3500 can be substantially heavier and taller than passenger vehicles.
Depending on the specific truck, a heavy-duty 3-ton, 3.5-ton, or 4-ton jack may be appropriate.
Don’t choose based on the truck’s badge alone. Check the vehicle’s actual specifications along with the jack’s rated capacity and lifting range.
Lift Height Matters
This is something that’s easy to overlook.
You can have a jack with plenty of weight capacity that still doesn’t lift high enough for your vehicle.
This becomes especially important with trucks and SUVs.
Compare the jack’s maximum lifting height with your vehicle’s approved lifting points and suspension travel before buying.
Lifted trucks may require specialized equipment rather than simply stacking blocks on a standard floor jack.
Low-Profile Jacks
If you work on sports cars or lowered vehicles, maximum capacity might not be your biggest problem.
Getting the jack underneath the car can be.
Low-profile floor jacks have a shorter minimum height, allowing the saddle to fit underneath lower lifting points.
Some also have an extended low-profile chassis that can reach farther underneath the vehicle.
Don’t Forget Jack Stands
This is the most important part of the article:
A floor jack is for lifting the vehicle. It is not a substitute for properly rated jack stands.
Never crawl underneath a vehicle supported only by a hydraulic jack.
Once the vehicle is raised, support it with appropriately rated jack stands positioned at manufacturer-approved support points before working underneath it.
Work on a solid, level surface and follow the procedures specified for your vehicle and lifting equipment.
Is a 3-Ton Floor Jack the Best All-Around Choice?
For many home garages working on ordinary passenger cars, SUVs, and light-duty pickups, a quality 3-ton floor jack can be a very versatile option.
It provides more capacity than many smaller jacks while still being manageable enough for normal garage use.
That doesn’t mean it’s right for every vehicle, though.
Someone working exclusively on a lightweight sports car may prioritize a low-profile design, while someone working on heavy-duty diesel pickups may need more capacity and lift height.
What to Look for When Buying a Floor Jack
Don’t shop based on tonnage alone.
Pay attention to:
Weight Capacity: Make sure it’s appropriate for the vehicles you’ll be lifting.
Minimum Height: Important for low cars.
Maximum Height: Especially important for trucks and SUVs.
Construction: Steel jacks are typically heavier, while aluminum models can be easier to move.
Saddle Size: A larger saddle can provide a more substantial contact area where appropriate.
Wheels and Casters: Good wheels make positioning a heavy jack much easier.
Overall Weight: A 100-pound shop jack isn’t something you’ll want to throw in the trunk regularly.
Final Thoughts
There’s no single floor jack that’s perfect for every garage.
If you’re working on normal cars and light-duty trucks, a 3-ton jack is often a useful place to start your search.
If you’re working on lowered cars, pay close attention to minimum height.
If you’re working on large trucks and SUVs, capacity and maximum lift height become especially important.
Most importantly, use the equipment correctly.
Buy a jack that’s properly rated for your vehicle, use the manufacturer’s approved lifting points, and never work underneath a vehicle supported only by a jack.
The right floor jack won’t just make garage work easier—it’ll be one of the pieces of equipment you reach for constantly.
