How Much Can Your Car Jack Hold?

The first step in selecting a scissor jack is to confirm the vehicle's weight. Passenger cars typically weigh between 1.2 and 1.8 tons, while compact SUVs can reach around 2 tons. Many beginners opt for the cheapest jack available, overlooking the critical importance of its rated load capacity. This oversight can cause the jack to tilt or even break during lifting, creating serious safety hazards.

So my opinions are:

• The rated load capacity should exceed the vehicle's total weight: It's generally recommended to choose a jack with a capacity 30% to 50% higher than the vehicle's weight. For example, for a 1.5-ton sedan, selecting a jack rated for over 2 tons is safer.

• Consider the load position: Some SUVs have different weight distributions between the trunk and tires. If lifting a fully loaded vehicle, the jack's load capacity should be correspondingly higher.

• Check specification labels: Reputable brands clearly mark the rated tonnage on their jacks. Avoid purchasing unlabeled or ambiguously marked products just to save money.

Remember that load-bearing selection directly impacts safety—never overlook it.

What Influences Durability of Scissor Jacks?

The durability of scissor jacks primarily depends on material quality and manufacturing processes.

For common steel and alloy jacks, thickness and weld quality directly impact service life. I personally recommend beginners choose models with all-steel construction and effective surface rust prevention. Additionally, gear and screw precision is critical—severe screw wear causes uneven lifting. Years of DIY experience have taught me: it's better to spend a little more on a reliable jack than to save money on a product prone to failure.

Choose a Compact Jack for Small Storage

Compact cars and SUVs have limited interior space, especially in the trunk and spare tire area. Even if a jack can handle the weight, it's difficult to carry one in the vehicle if it's too large or bulky. When selecting a compact and portable jack, keep the following points in mind:

• Folding Design: Compact folded length for easy storage in trunks or rear wheel wells.

• Weight Control: Typically 5–8 kg for effortless handling by a single person.

• Included Storage Case: Prevents loose parts, enhancing safety and organization.

• Ergonomic Handle or Ratchet Handle Design: Reduces exertion during operation, especially for roadside tire changes or emergency repairs.

My personal car jack folds down to less than 50 centimeters in length, making it lightweight and easy to store. In critical moments, it can be carried with one hand.

Manual vs. Ratchet Scissor Jacks

Scissor jacks can be categorized by operation method into manual screw jacks and ratchet jacks. Manual screw jacks feature a simple, durable design but require more physical effort; ratchet jacks offer easier operation and faster lifting speed, making them suitable for beginners. My experience suggests that if you frequently work alone or have children in the vehicle, a ratchet jack reduces physical exertion and lowers operational risks. Regardless of the type, always follow the instructions to properly position the jack's fulcrum and ensure the vehicle remains stable.

Tips to Using the Scissor Jack for Your Vehicle

Even if you choose the right jack, proper technique is equally important. Here's what I've learned from years of DIY experience:

Select level ground

Avoid slopes or soft surfaces. Place boards or bricks under wheels if necessary to enhance stability.

Use wheel chocks

This prevents vehicle slippage, significantly reducing safety risks—especially when working on inclines.

Position jack correctly

Place the jack at the support points specified in the vehicle manual to avoid damaging the chassis or exhaust system.

Raise and lower slowly

Sudden movements may cause the jack to tilt or the vehicle to sway. After each small lift, check the jack's stability.

Maintain the jack regularly

Lubricate the screw and inspect gear wear. Avoid prolonged storage in damp environments to prevent rust.

Carry spare accessories

Prepare a pair of small gloves and a simple jack support plate to enhance operational safety.

Before attempting the maneuver for the first time, beginners should practice several times on level ground to become familiar with the rhythm of raising and lowering the bike and the support points.

My Final Notes:

With these detailed adjustments, whether changing tires, inspecting the undercarriage, or performing occasional minor repairs, it's sufficient for both compact cars and family SUVs. By mastering these techniques, you can truly transform the scissor jack into an essential daily companion for driving safety.
