2T or 8T air jack – which lifting capacity should you choose for the vehicles you work on?

In the morning, you work on a standard passenger car, then an SUV comes in, and later in the day – a van. That is when it quickly becomes clear that one air jack does not always suit everything.

Too little lifting capacity limits you with heavier vehicles. On the other hand, if you mostly work on passenger cars, there is no point paying for an 8T model. In this article, we will show you when 2T is enough and when it is better to go for something bigger.

But first, remember one very important thing:

Do not choose the lifting capacity with no margin

If you work only on light passenger cars, 2T may be enough. The problem starts when a heavier SUV or van rolls into the bay.

So do not look only at whether the jack can theoretically handle it. Look at the vehicles you actually work on. If, besides passenger cars, you also get heavier vehicles, it is better to move up a level right away.

But before you click “buy now,” let us go through the most popular models.

2T air jack – who is it a good choice for?

A 2T air jack makes sense if you mostly work on lighter passenger cars. It will do the job for tyre changes, brake work, and simple suspension repairs. It is also the cheapest option, so if you mainly work on your own car or simply do not deal with larger vehicles, there is no point paying extra for lifting capacity you are not going to use.

3T / 3.5T air jack – the most versatile option?

A 3T or even 3.5T air jack is a good choice if you mostly work on passenger cars, but from time to time you also get a heavier estate car, crossover, or smaller van. It gives you more margin than a 2T model, while still avoiding a lifting capacity you would be paying extra for without really needing it in day-to-day work.

If you run a tyre shop with a mixed flow of vehicles, this will be the safer option.

4.5T air jack – when is it worth stepping up?

If you work on a passenger car in the morning and an hour later an SUV or a larger estate car rolls into the bay, 4.5T starts to make sense very quickly. With that kind of mix of vehicles, you do not have to keep wondering every time whether 3T is once again going to be a close call.

It is a good lifting capacity for a car service that sees heavier passenger cars, SUVs, and some vans. In other words, not a place where you spend the whole day working only on small hatchbacks, but a car service with a more mixed flow of vehicles where something bigger keeps turning up.

8T air jack – when is it a real need rather than overkill?

An 8T air jack makes sense when your car service regularly works on vans and light commercial vehicles. If these vehicles are a regular part of your day-to-day work, 8T is not overkill – it is simply the kind of equipment you need to have. It is a must-have wherever larger vehicles come in on a daily basis.

One stronger air jack or two with different lifting capacities?

“I mostly work on passenger cars, but once a week a heavier van comes in. I do not want to turn that kind of vehicle away. So is it better to get one stronger air jack or two different ones?”

If larger vehicles come in only occasionally, two air jacks give you more flexibility. The lighter one handles passenger cars on a daily basis, while the stronger one is there for vans and light commercial vehicles. But if larger vehicles are a regular part of your work, it is better to go straight for one stronger model.

What should you look at apart from lifting capacity?

Lifting capacity is not everything. Also check whether you can slide the air jack under the vehicle and move it around the car service comfortably.

What should you look at?	What should you check exactly?	What does it tell you in practice?	Example
Closed height	Whether the air jack will fit under the vehicle at all	The lower the starting point, the easier it is to slide it under lower passenger cars	The LS-220 3.5T has a closed height of approx. 14 cm
Lifting height	How high it actually lifts the vehicle	This determines whether you can comfortably work on a wheel, brakes, or simple suspension jobs	The tall 4.5T model lifts up to 44 cm
Wheels and manoeuvrability	Whether you can move the air jack easily under the vehicle	With frequent use, not only the lifting capacity matters, but also whether you are not wrestling with the equipment	The tall 4.5T model has wheels measuring 79 × 35 mm
Stability	Whether the model has a telescopic guide and a rubber pad at the lifting point	This reduces vehicle sway and improves confidence while working	These features are available in the 2T, 4.5T, and 8T models

When is an air jack not the best choice?

An air jack will not always be the best choice. If you get a low car in the workshop, you may have trouble sliding it under the sill. The same applies to cars with low ground clearance, body add-ons, or lowered suspension.

Also remember that an air jack works best for simpler jobs, such as changing wheels, brakes, or doing basic suspension work. If you do more advanced mechanical work and need convenient access to the underbody, it is better to go for a two-post lift.

Quick cheat sheet – which lifting capacity should you choose?

• 2T – if you mostly work on light passenger cars and do not want to pay for extra capacity you will not use.
  
  
• 3T – a good choice for most typical passenger cars and for a car service where something heavier comes in from time to time.
  
  
• 4.5T – when, alongside passenger cars, you also regularly work on SUVs, heavier estate cars, and some vans.
  
  
• 8T – if you work on vans and light commercial vehicles every day. With that kind of workload, it is simply equipment you need to have.

If you match the lifting capacity well to your day-to-day work, the equipment will simply be more convenient and will not start limiting you with the first heavier vehicle that comes in.

FAQ – the most common questions

• Can you leave a car supported only by an air jack?

No. An air jack is used for lifting and lowering the vehicle. Once the vehicle is raised, it must be supported with axle stands.

• What kind of surface should you use an air jack on?

Only on a flat, solid surface. This is important for the stability of the jack and for safe work.

• Is a 24 l compressor enough to work with an air jack?

Yes, as long as it maintains a stable working pressure of 6-10 bar. The tank size itself is not that important here.

• Is 2T enough for a passenger car?

Yes, if you mostly work on lighter passenger cars. With heavier SUVs and vans, 2T will quickly prove not to be enough.

• Is 3.5T the best choice for a tyre shop?

In many cases, yes. It is a good middle ground if you work on passenger cars every day, but something heavier comes in from time to time.

• What lifting capacity should you choose for an SUV?

If SUVs come in only occasionally, 3T is often enough. If you work on them regularly, it is better to look at 4.5T.

• Should you go straight for 8T for a van?

If vans and light commercial vehicles are a regular part of your work, yes.

• Is it better to get one stronger jack or two different ones?

One model is enough if you work on similar vehicles. Two make more sense when you mainly work on passenger cars, but a larger vehicle comes in from time to time.
