What size jack stands do I need? Matching tonnage to vehicle weight

In the United States, service stands are evaluated under ASME PASE standards, where published ratings typically represent the capacity of a pair across an axle. For example, TONDA lists a 3 Ton rating supporting up to 6,000 lb per pair, and KOERZORE lists a 3 Ton capacity supporting 6,000 lb per pair, while ANTPOWER describes its 3 Ton (6,600 lbs) rating per stand. Check your driver door pillar certification label for Gross Vehicle Weight Rating (GVWR) and axle ratings (GAWR) to choose appropriate capacity.

• Small passenger cars: A 2 ton pair suits lightweight vehicles. BIG RED lists the T42202 with a 2 ton (4,000 lb) capacity and a height range of 10-13/16 inches to 16-9/16 inches for small cars, SUVs, and light duty trucks.
• Sedans, crossovers, and SUVs: A 3 ton pair adds load margin and height. ANTPOWER lists a 3 Ton (6,600 lbs) capacity (11.22 to 16.77 inches), YELLOW JACKET lists 3 ton (6,600 lb) capacity (10-7/8 to 16-9/16 inches), PRUTHY lists 3 ton (6,600 lb) capacity (11.4 to 16.9 inches), KOERZORE lists 3 Ton (6,600 Lb) capacity (11-1/4 to 16-3/4 inches), and TONDA lists an extra-tall 3 Ton set reaching 13.39 to 21.06 inches.
• Trucks, vans, and large SUVs: Full-frame vehicles use 6 ton stands for stability and reach. Pro-LifT lists a 6 ton capacity (16 to 23-1/2 inches) for trucks, BIG RED lists the T46002A at 6 ton (12,000 lb) capacity (15-3/8 to 23-13/16 inches), and SENKEYFE lists 6 ton (13,200 lb) capacity (15 to 23 inches).
• Commercial equipment: BIG RED lists the ATZ120005R with a 12 ton (26,400 lb) capacity and a 12-5/8 to 18-1/8 inch range.

Jack stand sizes, capacities, and height ranges compared

Height range varies by design. For example, BIG RED lists a 16.53-inch maximum height on the 2 ton T42202, TONDA reaches 21.06 inches on its 3 ton stand, and Pro-LifT reaches 23-1/2 inches. Minimum collapsed height also matters: Pro-LifT starts at 16 inches and BIG RED lists 15-3/8 inches on the 6 ton T46002A, whereas SENKEYFE lists an 11-inch minimum height on its 6 ton stand.

Watch for listing contradictions: BIG RED lists the T46002A as 6 ton (12,000 lb) in its title, but the spec table states 2 ton. The BIG RED ATZ120005R title claims 12 ton (26,400 lb), but its spec table states 3 ton. SENKEYFE lists 15 to 23 inches in its title, but bullet points specify 11 to 23 inches. Rely on primary maker model specifications over unverified spec table cells.

How to choose and position jack stands safely: the checklist

1. Check door jamb ratings. Find GVWR and axle ratings on your driver door pillar to match stand capacity.
2. Measure required lift height. Ensure maximum height clears tires off the floor and collapsed height slides under lift points.
3. Verify ASME PASE compliance. Look for ASME PASE compliance (cited by ANTPOWER, KOERZORE, and BIG RED) or ANSI/PALD (cited by Pro-LifT).
4. Choose locking style. Select between ratcheting sawtooth bars, manual pin locks, or double-locking mechanisms.
5. Check base dimensions. Wider bases improve stability: BIG RED lists a 10.6 by 9.3 inch base on the 6 ton T46002A, TONDA lists 7.2 by 8.86 inches, and KOERZORE lists 7.7 by 7.7 inches.
6. Park on solid, level concrete. Only support vehicles on flat concrete slabs. Never use asphalt, dirt, or gravel.
7. Use factory lift points. Support vehicles only at reinforced pinch welds or frame rails named in your vehicle owner manual.
8. Lower slowly and verify stability. Lower floor jack pressure gradually onto stand saddles, then shake the vehicle gently before crawling underneath.

Ratcheting vs pin-style jack stands

• Ratcheting sawtooth stands: A ductile iron column with angled teeth locks automatically into an internal pawl. Models like ANTPOWER offer quick adjustments without loose pins.
• Pin-type stands: A steel post with drilled holes secures via a heavy pin through the collar. The BIG RED ATZ120005R uses an adjustable steel pin on a tether, eliminating ratchet teeth.
• Double-locking stands: Combines a ratcheting bar with a manual safety pin. Models from Pro-LifT, YELLOW JACKET, PRUTHY, KOERZORE (with 0.7-inch increments), and SENKEYFE slide a steel pin under the ratchet bar to block accidental release.

Matching your floor jack to your jack stands

To position your stands safely, your floor jack must raise the vehicle high enough to clear the collapsed stand height.

Frequently Asked Questions

Are jack stand weight ratings per stand or per pair?

Under ASME PASE standards, ratings represent capacity per pair across an axle. TONDA lists a 3 Ton set supporting up to 6,000 lb per pair, and KOERZORE lists 6,000 lb per pair. However, ANTPOWER lists 3-ton (6,600 lbs) capacity per stand. Always confirm on the product label whether the rating applies per stand or per pair.

Can I use 2 ton jack stands for an SUV?

Some makers, including BIG RED for the 2 ton (4,000 lb) T42202, list compact SUVs among compatible vehicles. However, a 16.53-inch maximum height may not lift larger SUV tires clear of the ground. For heavier SUVs, 3 ton models (like TONDA reaching 21.06 inches) or 6 ton stands provide safer clearance and capacity.

What height range do I need for a truck or SUV?

Trucks require stands that reach tall frame rails. TONDA lists an extra-tall 3 ton stand reaching 21.06 inches, while 6 ton truck stands from Pro-LifT and SENKEYFE reach 23-1/2 inches and 23 inches respectively. Measure from the ground to your frame lift points to ensure sufficient reach.

Where should jack stands be placed under a vehicle?

Place stands only at factory support points listed in your vehicle owner manual, such as reinforced pinch welds or frame rails. Never place stands under floor pans, suspension arms, or steering linkages.

Can I use jack stands on asphalt, gravel, or dirt?

No. Use jack stands only on solid, level concrete. Pyramid feet exert high point loads that sink into hot asphalt or shift on loose dirt and gravel.

How many jack stands do I need for routine maintenance?

Routine maintenance on a single axle requires a pair of jack stands. To support both axles off the ground, read our guide on how many jack stands do you need for stability rules.
