Floor Jack Buying Guide: What Every Mechanic Needs to Know
The Most Important Safety Tool in Your Garage
A floor jack is the piece of equipment that goes under your car. Get this wrong and you're looking at a serious safety risk. Get it right and you have a tool that lasts decades. Here's what to know before you buy.
Capacity: How Much Do You Actually Need?
Floor jacks are rated by the maximum weight they can lift. The number you need depends on your vehicle:
- 2 ton (4,000 lbs): Fine for most compact cars and sedans
- 3 ton (6,000 lbs): The sweet spot. Handles trucks, SUVs, and most passenger vehicles. Recommended for most home mechanics.
- 3.5β4 ton: For heavy-duty trucks, large SUVs, and 3/4-ton+ vehicles
Note: You never lift the whole car at once β you lift one corner. But capacity matters for overall jack quality and durability, so don't go minimum.
Steel vs. Aluminum
Steel jacks are heavier (35β60 lbs) but more durable and significantly cheaper. Great for home garage use where you're not moving the jack in and out of a truck constantly.
Aluminum jacks are lighter (15β25 lbs) and easier to transport. Worth it for mechanics who travel, but you'll pay 2β3x more for the same capacity.
For a home garage: buy steel. For a mobile mechanic: consider aluminum.
Low Profile vs. Standard
Low-profile jacks (min height 2.5"β3") are essential for sports cars and lowered vehicles. Standard jacks (min height 4"β5") work for most stock-height trucks and SUVs. Check your vehicle's ground clearance before buying.
Lift Height
Standard floor jacks lift to 18"β20". That's enough for changing tires and basic brake work. If you're doing suspension work on a lifted truck, look for a jack with 20"β24" max height.
Jack Stands: Non-Negotiable
Never work under a car supported only by a floor jack. Floor jacks can fail. Always use jack stands rated for your vehicle's weight after you lift it. This is not optional.
