can you use 2 jacks on a car

[CaliLynn]

Using two jacks on a car simultaneously is not safe and is strongly discouraged by automotive professionals. The primary risk is a catastrophic loss of stability. Vehicles are designed to be supported at specific, reinforced points on their frame. Using two separate jacks, especially hydraulic floor jacks, creates four independent points of contact that can easily shift or sink unevenly. This puts immense and unpredictable stress on the vehicle's chassis and dramatically increases the likelihood of the car falling.

Risks of Using Two Jacks:

Risk Factor	Why It's Dangerous
Instability	Two jacks cannot be perfectly synchronized. One may lower slightly, transferring the entire vehicle's weight to the other, causing it to kick out.
Chassis Stress	Lifting from non-reinforced points can bend or damage the vehicle's frame or body panels.
Jack Failure	Most jacks are not rated for the side-load forces that occur when a vehicle shifts on an unstable base.
Ground Condition	Uneven or soft ground greatly amplifies these risks, making a collapse almost inevitable.

The correct and safe method is to use a single jack for lifting, followed immediately by positioning jack stands under the vehicle's reinforced lift points. Jack stands are mechanically locked in place and designed to hold the weight securely. The jack should then be slightly lowered so the vehicle rests entirely on the stands. This creates a stable, redundant safety system. The jack can remain as a secondary safety measure, but the primary support must always be jack stands. Never work under a vehicle supported only by a jack.

No way, that's asking for trouble. I learned this the hard way trying to rotate my tires in the driveway. I had the car up on two jacks and just barely nudged it—the whole thing rocked like a boat. One jack slipped and the car dropped a few inches. My heart just about stopped. Now I only use my floor jack to lift one corner at a time, and I always, always slide a jack stand under there before I get my hands anywhere near the wheels. It's not worth the risk.

From an engineering standpoint, it's a terrible idea due to statics and stability. A vehicle on two jacks forms an unpredictable system. Any minor disturbance—a breeze, you pushing on a wrench—can create a moment force that the jacks aren't designed to resist. They can pivot and fail. The only safe procedure is to create a stable base using jack stands, which have a wide footprint and a positive mechanical lock. The jack is for lifting; the stands are for holding.

I wouldn't feel comfortable doing that. It just doesn't seem stable enough. What if the ground isn't perfectly level? What if one of the jacks has a small leak? There are too many variables. I always follow what my dad taught me: lift with the jack, set the stands, and then give the car a good shake before you go under it. That extra minute setting up the jack stands is the best insurance policy you can get for a simple brake job or oil change.

Absolutely not. In the shop, we see the results of shortcuts like this. It's never a simple "oops." A car falling off jacks can cause severe injury or death. The proper protocol is non-negotiable: one jack for lifting, then support the vehicle on four high-quality jack stands placed squarely on the manufacturer's specified lift points. This creates a stable, secure platform. The jack can be left in place as a backup, but it should not be bearing the load. Your safety is worth the right equipment and the five extra minutes it takes to do the job correctly.
