Is it Safe to Use 4 Jack Stands at Once?

When it comes to automotive maintenance or repairs that require lifting a vehicle off the ground, jack stands are essential tools. They provide a stable and secure support system, ensuring the safety of mechanics and enthusiasts alike. While using a pair of jack stands is common, some may wonder if it is safe to use 4 jack stands at once. 

In this article, we will explore the safety aspects of using four jack stands simultaneously and discuss essential precautions to take when performing such tasks.

Is it Safe to Use 4 Jack Stands at Once

Using four jack stands at once can be safe if they are high quality, have sufficient weight capacity for the vehicle, positioned correctly at recommended lift points, and placed on a level surface.

Proper weight distribution and stability checks are essential for ensuring safety during maintenance tasks.

Important Considerations When Using Four Jack Stands

Here are some important considerations:

1. Quality of Jack Stands

Ensure that the jack stands are of good quality and have a weight capacity suitable for your vehicle. Cheap or poorly made jack stands may be less reliable and more prone to failure.

2. Weight Capacity

Make sure the combined weight capacity of all four jack stands is greater than the weight of your vehicle. The weight capacity is usually indicated on the jack stands’ labels.

3. Proper Positioning

Place the jack stands at the recommended lifting points on your vehicle. Refer to the vehicle’s owner’s manual for the correct locations. Using improper lifting points can lead to damage or instability.

4. Level Surface

Always use jack stands on a level and firm surface to ensure stability and prevent accidents.

5. Chock Wheels

Before lifting the vehicle, make sure to chock the wheels that are still on the ground. This prevents the vehicle from rolling or shifting during the lifting process.

6. Lifting Sequence

If you are lifting the entire vehicle, it’s important to lift it evenly and gradually on each side. Do not lift one side entirely and then move to the other, as it can cause instability.

Why Four Jack Stands Are Preferred?

Using four jack stands provides increased stability and load distribution compared to using just two stands. When all four corners of the vehicle are supported, the weight is evenly distributed, reducing the risk of the vehicle tilting or tipping over.

This setup also ensures a more level working platform, which is especially crucial when performing tasks that require precision and accuracy.

Factors to Consider Before Using Four Jack Stands

Before using four jack stands, there are essential factors to consider to ensure the safety and effectiveness of the setup.

1. Weight Capacity

Each jack stand has a specific weight capacity, which should be clearly marked by the manufacturer. 

It is vital to check the weight of the vehicle and ensure that the combined weight does not exceed the capacity of the four jack stands. Using stands with insufficient capacity can lead to structural failure and endanger the mechanic.

2. Surface Stability

The surface on which the vehicle and jack stands are placed must be stable and level. Uneven or soft surfaces can cause the stands to sink or shift, leading to an unstable working environment. It is advisable to use jack stands on a flat, solid surface for maximum safety.

3. Jack Stand Quality

Investing in high-quality jack stands is crucial for ensuring safety during repairs. Inferior stands may have manufacturing defects or weak points that could compromise their structural integrity. 

Always purchase jack stands from reputable manufacturers and check for any signs of damage or wear before each use.

4. Proper Placement

Correctly placing the jack stands is essential to distribute the vehicle’s weight evenly. Consult the vehicle’s owner’s manual to locate the recommended lifting points.

Placing the stands at the wrong spots can damage the vehicle’s frame or body, leading to costly repairs and safety hazards.

Safety Measures While Using Four Jack Stands

Using four jack stands requires careful attention to safety measures to minimize risks and potential accidents.

1. Engage Emergency Brake

Before lifting the vehicle, engage the emergency brake to prevent any accidental movement. This additional measure ensures that the vehicle remains stationary while it is lifted and supported by the jack stands.

2. Use Wheel Chocks

Place wheel chocks on the wheels that remain on the ground to further prevent the vehicle from rolling or shifting. Wheel chocks provide an extra layer of security and stability during the repair process.

3. Secure Lifting Points

Ensure that the lifting points on the vehicle are clean and free from debris. Securely position the floor jack under these points to avoid any slippage or damage to the vehicle’s undercarriage.

4. Work on a Flat Surface

Performing maintenance on a flat surface reduces the risk of accidents caused by the vehicle rolling or shifting. Avoid working on slopes or inclines whenever possible.

Alternatives to Using Four Jack Stands

While using four jack stands is generally safe when done correctly, there are alternative methods for lifting a vehicle for specific tasks.

1. Two Jack Stands and Tires

For some maintenance jobs, using two jack stands and leaving the other two wheels on the ground may suffice. 

However, this method should only be employed when the tasks do not require lifting the entire vehicle off the ground.

2. One Jack Stand and a Floor Jack

Another option is to use a single jack stand along with a floor jack. This approach is suitable for tasks that involve working on one side of the vehicle while keeping the other side grounded.


Using 4 jack stands at once can be safe and effective if done correctly. However, it is essential to prioritize safety above all else and follow the best practices outlined in this article. Remember to invest in high-quality jack stands, use identical models, know your vehicle’s lifting points, and calculate the total weight of the vehicle.

Following these guidelines will significantly reduce the risk of accidents and ensure a smooth and secure working environment. Always exercise caution and, when in doubt, consult a professional mechanic or car expert for guidance.


Is it safe to use four jack stands simultaneously to support a vehicle?

Yes, it is generally safe to use four jack stands at once, given that they are of high quality and used properly. Four jack stands provide excellent stability and are commonly used for tasks that require all four wheels to be lifted off the ground, such as tire rotation or extensive repair work.

Are there any advantages to using four jack stands instead of just two? 

Yes, using four jack stands offers several benefits compared to using only two. These include enhanced stability, improved weight distribution, and a safer working environment.

Is there a difference in quality among different brands of jack stands?

Yes, not all jack stands are created equal. Quality can vary significantly between different brands and models. It is essential to invest in reputable and certified jack stands to ensure safety and reliability during automotive tasks.

How do I determine the appropriate weight capacity for the jack stands I require? 

To determine the necessary weight capacity, you should know your vehicle’s gross weight and choose jack stands with a capacity that exceeds this weight. Gross vehicle weight can often be found in the owner’s manual or on the manufacturer’s website.

Is it safe to keep my vehicle supported by jack stands for an extended duration? 

While jack stands are designed for stability and safety, it is not recommended to leave a vehicle on them for an extended period. Jack stands are primarily intended for temporary use during automotive tasks.
