Two-Post vs. Four-Post Car Lift: Which Is Right for Your Garage?
By Holly, Founder of Bay One Auto EquipmentUpdated
Choosing between a two-post and a four-post lift is the biggest call you'll make for your garage, and the two are built for different jobs. Pick the one that fits how you actually use your cars and you'll reach for it every weekend. Pick the other and you'll work around it for years. Here's the straight answer first, then everything you need to back it up.
The quick answer: buy a two-post if you mostly repair cars. Brakes, tires, suspension and exhaust are all faster when the wheels hang free. Buy a four-post if you mostly park or store cars, or if your garage only has 110V power. If your time splits evenly, choose for the job you do most and add a bridge jack to a four-post for the wheel work.

Our top picks, reviewed
Every lift below is one we sell, and every spec comes from its manufacturer. We've been as clear about each one's weak spots as its strengths.
Triumph NT-11 two-post lift
For home and small-shop mechanics who want a heavy-duty two-post without the height of an overhead model.
Pros
- 11,000 lbs of capacity, with 2,750 lbs rated per arm pad.
- At 116 inches tall, it fits buildings where a 145-inch overhead lift won't.
- Asymmetric arms set the car back between the posts, so the doors open wider.
- Single-point lock release, and truck adapters come in the box.
Cons
- Needs a dedicated 220V circuit and a permanent, anchored installation.
- The floor plate between the columns is something you'll roll creepers and jacks over.
- Long, heavy trucks balance better on symmetric arms, such as the NT-16's.
Key specs: 11,000 lbs · 72" lift height · 116" tall · 138" wide · 102" drive-thru · 220V
Call for better pricing on this item: 1-800-771-1278
Triumph NTO-10A overhead two-post lift
For garages with 12 feet or more of clear height, where you want nothing on the floor between the posts.
Pros
- Clear floor between the columns for a transmission jack, creeper or oil drain.
- An electric safety cutoff stops the lift before a tall vehicle reaches the overhead bar.
- Truck adapters in 1.5, 3 and 6 inches are included.
- About 40 seconds to full height on a 3 HP motor.
Cons
- At 145 inches, it's too tall for many home garages.
- Needs 220V and a slab of at least 4 inches at 3,000 PSI for anchoring.
- Rated for 10,000 lbs, less than the NT-11.
Key specs: 10,000 lbs · 72" lift height · 145" tall · 133" wide · 96" drive-thru · 220V

AMGO BP-9 base plate two-post lift
For lower ceilings and low cars, when you still want a true two-post.
Pros
- At 108 inches, it's the shortest fixed two-post we carry, built for ceilings of 9 feet and up.
- The arms reach down to 3 5/16 inches, which helps with low cars.
- About 37 seconds to full height.
- AMGO's warranty: 5 years structural, 3 years hydraulic, 2 years electrical.
Cons
- 9,000 lbs of capacity, so it isn't the lift for heavy trucks.

Triumph NSS-8 four-post lift
For anyone who wants two cars in one bay, or a safe place to keep a car for months.
Pros
- The car rides on its own tires and rests on mechanical locks, not hydraulic pressure.
- Ten lock positions with a single-point release.
- Free-standing with a caster kit, so there's no drilling into your slab.

Cons
- Needs a 30-amp, 110V receptacle, which isn't a standard wall outlet.
- Wheel work takes a jack or a bridge jack, sold separately.
- With 69 inches under the runway, a tall SUV won't park beneath it. The NSS-8XLT gives you 79.

How to choose between a two-post and a four-post lift
Here's how the two styles compare on the questions that settle most decisions.
| Question | Two-post lift | Four-post lift |
|---|---|---|
| How it holds the car | Four arms under the frame lift points | On its tires, on two runways |
| Wheels-off work | Ready as soon as the car is up | Needs a jack tray and jack, or a bridge jack |
| Parking one car over another | Not built for it | Built for it |
| Loading | Set each arm at the correct lift point | Drive onto the runways and go up |
| Floor anchoring | Anchored to the slab (the C-7000 is the exception) | Many models are free-standing with casters |
| Power in our lineup | 220V, except the 110V C-7000 | 110V, except the 220V AMGO PRO-12SX |
| Capacity in our lineup | 7,000 to 16,000 lbs | 7,000 to 12,000 lbs |
1. Start with the job you'll do most
Ask yourself two questions. Will you have wheels off most weekends? Do you need a second parking space? A yes to the first points to a two-post. A yes to the second points to a four-post. A two-post also lets you drop a transmission or subframe straight down, which a four-post's runways block.
2. Measure your ceiling, not the brochure
Ceiling minimums quoted online vary widely, so measure your own garage to the lowest point: the open door, the opener, lights and beams. Then check two things.
- The lift itself. Floor plate and base plate two-posts are short: 108 inches for the AMGO BP-9, 111 for the Triumph NT-9, 116 for the NT-11 and 120 for the NT-16. Clear floor models need far more: 145 inches for the NTO-10A and NTO-11A, and 174 to 198 inches for the AMGO OH-12.
- The car at height. On a two-post, add your tallest vehicle's height to the lift height. On a four-post, the top car's roof at your chosen lock height has to clear the ceiling while the car below fits under the runway. Under-runway clearance runs from 69 inches on the NSS-8 to 79 on the NSS-8XLT and 81.5 on the NOS10000.
Short on height? Start with our low ceiling car lifts, and see our guide to what size car lift you need for the full math.
3. Check your power
Every fixed two-post we carry needs a dedicated 220V circuit. Every Triumph four-post runs on 110V, though the NSS-8 and NSS-8XLT need a 30-amp, 110V receptacle that most garages don't have. Book a licensed electrician before delivery if you need either. Our 110V vs. 220V guide lists every model.
4. Look at your floor
A two-post is always bolted down, because two columns carry the whole load. Many four-posts aren't: the NSS-8, NSS-8 Classic, NSS-8XLT, NSS8X-1 and NSS-11 are free-standing with caster kits. Free-standing still needs good concrete. The NSS-8 calls for at least 4 inches at 3,000 PSI on a level floor. Ask us for your model's installation manual before you buy.
5. Plan the floor space
A two-post is wide but short: the NTO-10A is 133 inches across, and the length is just your car. A four-post is long: the NSS-8 is 106 inches wide and 195 inches long with its ramps. Leave room to open a door and walk around.
6. Budget for the extras
Count everything before you compare prices: a bridge jack if you'll do wheel work on a four-post, an electrician, an installer, and a way to unload the freight. Installation isn't included, but we refer installers in your area. See our installation checklist.
New to lifts, or done this before?
- First lift: a four-post is the more forgiving choice. You drive on and go up, with no arms to place. A free-standing model also skips the anchoring.
- Experienced mechanics: a two-post pays you back in speed on every brake, suspension and drivetrain job. Choose a clear floor model if you use a transmission jack often.
Safety and ALI certification
Both styles are safe when installed and used as the manufacturer specifies. On a two-post, the pads must sit on your vehicle maker's lift points. On a four-post, check that the locks have engaged before anyone goes underneath. ALI certification means an independent lab tested that lift model to the ANSI/ALI ALCTV standard. In our lineup, the AMGO OH-10 is ALI certified. If your insurer or landlord requires it, tell us before you order.
Frequently asked questions
Can you store a car on a two-post lift?
For a few days while you work on it, yes. For a season, use a four-post. On a two-post the suspension hangs at full stretch the whole time; on a four-post the car rests on its tires as it would on the ground.
Can you do brakes and tires on a four-post lift?
Yes. Use the included jack tray with a bottle or floor jack for the occasional job, or add a bridge jack if you do wheel work often. Our rolling bridge jack guide matches jacks to lifts.
Does a two-post lift need 220V?
Every fixed two-post we carry does. The portable Triumph C-7000 is the one two-post that runs on 110V.
Which lift is better for low sports cars?
A two-post with low-reaching arms, such as the AMGO BP-9 at 3 5/16 inches, skips ramps entirely. On a four-post, check your front lip against the approach ramps. The NSS-8's runways lower to 5 inches.
Does a four-post lift have to be bolted down?
Not always. The Triumph NSS-8 family and NSS-11 are free-standing. The NOS10000 includes anchor bolts in case you want it permanent.
