How do I choose the right automotive jack and jack stands?

Choose a jack and jack stands by your vehicle’s actual weight, approved lifting and support points, clearance, and the height required for the job. The jack must lift the end or corner you’re raising, while the stands must support the vehicle after the jack is removed. Check the owner’s manual or service information first, then choose equipment with a suitable capacity margin, height range, saddle shape, and base for your car and garage floor. If the floor is uneven, the vehicle has unusual lifting points, or you only need to remove wheels, ramps or specialty adapters may be a better fit.

What capacity and height should your jack and stands have?

Start with the vehicle’s published curb weight, gross vehicle weight rating (GVWR), and front and rear axle ratings. Curb weight describes the vehicle in a specified unloaded condition; GVWR is the maximum permitted total weight with occupants and cargo. The axle ratings show how weight is distributed, which helps when you’re lifting only the front or rear.

Find the lifting points and support points in the owner’s manual or service information. A floor jack may lift at a designated front or rear point, while the stands may need to sit at separate reinforced points. Don’t assume that a visible subframe, suspension arm, fuel tank edge, or pinch weld can carry the load.

Choose a jack with a rated capacity comfortably above the load it will actually lift. The rating is not a target, and you shouldn’t work close to the limit. For a front-end lift, use the manufacturer’s front axle information as a reference, while allowing for uneven loading, passengers or cargo, and a jack that may not be centered perfectly. For a single corner, the relevant load is the weight transferred to that corner, not the whole vehicle. You still need a conservative margin and a jack designed for stable lifting at that position.

Each stand must be rated for the load it may carry, and the pair must be suitable for the raised end of the vehicle. Don’t divide the vehicle’s total weight mechanically and assume every stand will receive exactly one-quarter. Loads shift as the vehicle rises, and the surface or support points may not be perfectly equal.

Height matters as much as capacity. Measure the lowest ground clearance at the intended jack point and compare it with the jack’s minimum saddle height. Include enough room to roll the jack into position. At the top end, measure how high the vehicle must rise for the stands to reach the approved support points while leaving useful room for the work. The stands’ minimum and maximum support heights must cover that position without requiring an unstable or prohibited setting. A jack that can lift high enough is still unsuitable if its saddle can’t get under the car.

How do you choose a jack that fits your car and your garage?

For most home brake, suspension, oil, and underbody work, a hydraulic floor jack is easier to position and control than a small emergency scissor jack. A bottle jack can provide substantial lifting force in a compact body, but its height and narrow footprint may not suit a low car or a smooth garage floor. A scissor jack is generally intended for roadside wheel changes, not repeated workshop lifting or supporting a vehicle.

Use this selection process:

1. Measure the lowest access point and the manufacturer-approved lifting point. The jack’s minimum height must be lower than the available clearance, including room to roll the jack into position.
2. Measure the required lifting height. Include the height needed to place the stands securely, not just the height needed to get a tire off the floor. Check the jack’s maximum rated lift height and the stands’ usable support range.
3. Check the saddle. A broad, stable saddle is useful for a frame or designated lift pad, while a rubber pad or pinch-weld adapter may be needed to protect a narrow seam. The saddle must contact the specified point fully; an improvised block or loose adapter can slip.
4. Consider low-profile access. A low-profile floor jack helps with lowered vehicles and cars whose factory lift points sit close to the ground. It doesn’t make an unapproved lifting point safe.
5. Choose construction for the way you’ll use the jack. Steel jacks are usually heavier and can be durable; aluminum models are easier to move but may have different weight, cost, and long-term corrosion considerations. The material alone doesn’t prove safety.
6. Inspect the handle and wheels. A long, well-positioned handle gives better control, while swiveling rear casters make positioning easier. Wheels should roll freely on your actual floor without sinking into cracks or catching on joints.
7. Confirm that the jack remains stable throughout the lift. A long chassis can improve rolling stability as the saddle rises, but it also needs enough room to move. Never position a rolling floor jack where a wall, drain, slope, or obstruction prevents it from following the vehicle’s movement.

Which jack-stand features actually affect safety?

A stand’s load rating should be clearly marked and should apply to the individual stand, not only to a pair. Buy stands from a traceable manufacturer and look for the safety certification or standard claimed for the model in your country. A certification marking is useful only when it’s genuine and matches the documentation; an unverified logo or vague claim isn’t a substitute for a published rating.

The height-adjustment design determines how the stand is set and locked. Ratchet-style stands are quick to adjust, but the locking mechanism must fully engage and be checked visually. Pin-lock stands use a physical pin through the height tube, making the secured position obvious. Screw-lock designs allow fine adjustment and mechanical engagement. Use any style exactly as specified. Never rely on friction, a partially inserted pin, or a loose handle.

A wide, stable base helps distribute force on a sound, level floor. The feet should sit flat, and the stand shouldn’t rock. The saddle should match the vehicle’s approved support point. Some vehicles need a flat frame saddle; others need a rubber pad or a slot that fits a pinch weld. A saddle that contacts only an edge can deform the vehicle or let it slide.

Look for sound welds or castings, straight legs, protected adjustment parts, and corrosion resistance. Surface rust may be cosmetic, but deep pitting, bent metal, cracked welds, damaged teeth, a missing pin, or a stand that no longer locks is a reason to remove it from service. Store stands dry and protected from impacts, chemicals, and weather.

Use at least two stands when raising one end of a vehicle. Place them at the manufacturer-approved support points, at matching heights, and on the same solid, level surface. The hydraulic jack may remain lightly positioned as a backup only if it doesn’t interfere; it is never the sole support. A hydraulic system can lose pressure, and a jack can roll or shift.

How should you pair the jack and stands for the job?

Pair the equipment for the complete job, not by capacity alone. The jack must reach the lifting point, raise the vehicle high enough for the stands, and remain stable while the load transfers. The stands must fit the support points and have enough height and individual capacity for the end being supported.

Consider a brake job on the front axle. Verify the front lifting point, measure the clearance under it, and choose a jack that can reach that point and raise the front high enough for both stands. Place the stands at the specified left and right front support points, not under random suspension components. Lower the vehicle slowly onto both stands, confirm that each saddle is centered and locked, and check stability before removing a wheel or working underneath it. The jack alone must not support the car while you work.

Use four stands when the procedure requires the entire vehicle to be level or when you need both axles unloaded, such as for some underbody, exhaust, or suspension work. Raising all four corners requires extra care: follow a sequence that keeps the vehicle stable, chock the wheels that remain on the floor during the first lift, and use only approved support points. Don’t create a four-point setup on a sloped or uneven surface.

Ramps can be a better choice for an oil change or other work that needs only one end raised. They provide a broad contact area, but they must match the tire size and vehicle clearance, sit flat, and include a positive stop. They aren’t suitable when the wheels need to be removed or when the vehicle can’t be driven onto them safely.

Specialty adapters may help with pinch welds, jacking pucks, or manufacturer-specific lift pads. Use an adapter only when it’s designed for that point, fits securely, and doesn’t reduce the jack or stand’s stability. Never stack loose wood, bricks, blocks, or improvised spacers under a jack or stand.

What should you check before you buy or lift?

Use this checklist before placing an order or raising the vehicle:

• Read the owner’s manual for lifting and support points, axle information, warnings, and any required adapters.
• Record the vehicle’s curb weight, GVWR, front axle rating, rear axle rating, and the weight of cargo you may carry during the job.
• Compare the jack’s rated capacity and minimum and maximum height with the actual lifting point and required working height.
• Check each stand’s individual capacity, minimum and maximum height, saddle shape, and locking method.
• Confirm that the jack and stands have clear, permanent markings and traceable manufacturer information. Check current recalls, safety notices, and the applicable certification or safety standard rather than relying on an online seller’s title.
• Measure the garage floor. It should be hard, level, and strong enough for the wheels and stand feet. Avoid slopes, loose gravel, soft asphalt, floor drains, broken concrete, and transitions where a wheel can catch.
• Check that the jack can roll as its saddle rises and that doors, walls, and other equipment won’t obstruct it.
• Inspect new and stored equipment for shipping damage, rust, bent parts, leaking hydraulics, damaged wheels, worn saddle pads, and locking parts that fail to engage.
• Keep wheel chocks available for wheels that stay on the floor. Set the parking brake when appropriate, but don’t treat it as a substitute for chocks.
• Plan how you’ll lower the vehicle onto the stands before you lift it. After lowering, verify that both stands are fully engaged, centered, and stable.

Never work under a vehicle supported only by a hydraulic jack, scissor jack, bottle jack, or ramps that aren’t properly positioned. Lower the vehicle onto correctly placed stands before reaching underneath it, and keep hands and feet clear while transferring the load.

The setup is ready when the jack reaches the approved lifting point without forcing the vehicle sideways, the stands sit flat at equal and suitable heights, their locks are fully engaged, and the supported vehicle remains stable after the jack is lowered. If any of those conditions can’t be met, stop and choose different equipment or a different method.

Conclusion

Before buying, measure the vehicle instead of guessing from its size. Match the jack’s access and lift range to the actual lifting point, then match each stand’s rating, height, saddle, and lock to the approved support points. For a level garage and ordinary wheel-off work, a suitable floor jack and two properly rated stands are the usual starting point; ramps may be simpler for work that doesn’t require wheel removal. If the vehicle can’t be supported squarely and securely, don’t lift it until the method changes.

Frequently Asked Questions

Can I use the jack stands that came with my car?

Usually, the supplied equipment is intended for emergency wheel changes and may not provide the height, capacity, stability, or adjustment range needed for workshop work. Check its markings and the vehicle instructions. If they don’t clearly show that the equipment suits the vehicle and job, use purpose-built stands for repeated home repairs.

Do I need two or four jack stands?

Use at least two stands when supporting one end of the vehicle. Use four only when the procedure requires both ends raised or the vehicle level, and only on a solid, level surface with approved support points. Never support one corner with a single stand while the other side remains unsupported unless the manufacturer specifically provides a safe procedure for it.

Can I put a jack stand under the axle or suspension arm?

Only if the vehicle manufacturer identifies that location as a safe support point for the procedure. Some axles and suspension parts can support a load, while others can bend, move, or interfere with the work. Follow the service information rather than judging by appearance or convenience.

Is a higher-capacity jack always safer?

No. Capacity is only one part of the selection. A larger jack may not fit under the vehicle, may have an unsuitable saddle, or may be difficult to position on your floor. Choose a model with an appropriate capacity margin, the correct height range and contact point, and enough stability and control for the lift.
