Understanding Car Jacks And Lifting Points
Before we dive into the main topic, it’s essential to understand how car jacks work and where to place them. A car jack, also known as a scissor jack or hydraulic jack, is a device designed to lift a vehicle off the ground, giving you clearance to perform various tasks. There are two primary types of car jacks:
- Scissor jacks: These are the typical jacks that come with most vehicles. They are compact, lightweight, and designed for emergency situations, such as changing a flat tire.
- Hydraulic jacks: These are more heavy-duty and designed for lifting heavier vehicles or for use in professional settings, such as garages or mechanic shops.
To ensure safe lifting, you need to identify the correct lifting points on your vehicle. These are reinforced areas designed to support the weight of the car when lifted. Typically, lifting points are located near the wheels, and the exact location will vary depending on the vehicle make and model.
Lifting Points And Jacking Locations
When selecting a jacking location, it’s crucial to consult your vehicle’s owner’s manual or the manufacturer’s instructions. Some common lifting points include:
- Front and rear frame rails: These are the longitudinal members that run along the sides of the vehicle, providing a solid anchor point for the jack.
- Axle or suspension points: These are reinforced areas near the wheels, designed to support the weight of the vehicle.
- Specialized jacking points: Some vehicles, such as trucks or SUVs, have dedicated jacking points, which may be marked with a picture of a car and a jack.
It’s essential to remember that not all areas of the vehicle are suitable for lifting. Avoid using the following areas, as they can cause damage or compromise the structural integrity of the vehicle:
- Fenders, doors, or other body panels: These are not designed to support the weight of the vehicle and can bend or break under the pressure.
- Exhaust system or fuel lines: Lifting near these areas can cause damage, leading to expensive repairs or even safety hazards.
The Safety Implications Of Using Two Jacks
Now that we’ve covered the basics of car jacks and lifting points, let’s address the question: Can you put a car on two jacks? The short answer is, it’s not recommended. Here’s why:
Safety Risks:
Using two jacks can create a high center of gravity, making the vehicle more prone to tipping or falling off the jacks. This can lead to serious injuries or even fatalities. Additionally, if one jack fails or shifts, the entire vehicle can come crashing down.
Weight Distribution:
When you use two jacks, the weight of the vehicle is concentrated on a smaller area, which can cause the jacks to sink into the ground or become unstable. This uneven weight distribution increases the risk of accidents and makes it more difficult to control the vehicle.
Reduced Stability:
Lifting a car on two jacks reduces the overall stability of the vehicle, making it more susceptible to wind, uneven ground, or other external factors that can cause it to tip or fall.
Why Two Jacks Are Not A Substitute For Ramps Or Lifts

- Ramps and lifts are designed to distribute the weight of the vehicle more evenly, providing a wider base of support and increased stability.
- These devices are constructed with safety features, such as locking mechanisms and weight capacity ratings, to ensure a secure lifting experience.
- Ramps and lifts often provide more clearance than jacks, allowing for easier access to the underside of the vehicle.
When To Use Two Jacks (And How To Do It Safely)
While it’s not recommended to use two jacks as a primary lifting method, there may be situations where it’s necessary, such as:
Emergency Situations:
In the event of a flat tire or other emergency, using two jacks may be the only option to get the vehicle off the ground quickly.
Professional Settings:
In some professional settings, such as a mechanic shop or dealership, using two jacks may be acceptable under close supervision and with proper training.
If you must use two jacks, follow these safety guidelines:
- Choose a level, firm surface to lift the vehicle.
- Use high-quality, heavy-duty jacks rated for your vehicle’s weight.
- Position the jacks near the lifting points, ensuring they are stable and secure.
- Lift the vehicle in small increments, checking the stability and weight distribution at each stage.
- Use jack stands for added support and safety.
- Always refer to the vehicle’s owner’s manual and manufacturer’s instructions for specific guidance on lifting and jacking.
Conclusion:
In conclusion, while it’s technically possible to put a car on two jacks, it’s not a recommended practice due to the associated safety risks and weight distribution concerns. When lifting a vehicle, it’s essential to prioritize safety and use proper lifting equipment, such as ramps or lifts, whenever possible. If you must use two jacks, follow the safety guidelines outlined above and consult with a professional if you’re unsure about any aspect of the process. Remember, safety should always be your top priority when working under your vehicle.
