How to choose a trolley jack
There are certain pieces of equipment that should be present in any car garage. One of those is the ever-reliable trolley jack lift – a trusty and incredibly strong garage sidekick that does all the heavy lifting, so you don’t have to. Now, trolley jacks come in many different shapes and sizes, so if you’re new to the world of jack lifts, or you’re simply looking to find the right jack for your particular job, we’re here to help.
What is a trolley jack?
A trolley jack is one of the absolute cornerstones of the gear you'll need in a garage or to go with your vehicle. It doesn't matter whether you need one in the boot for emergencies or parked in the corner of your service garage business - you’ll definitely require a trolley jack if you plan on doing any work on a car.
A trolley jack is a mobile device that enables you to lift your vehicle to carry out work underneath, whether that’s to change the tyres, work on brake assemblies or carry out just about anything else you might need to. The aim is to lift the vehicle with the minimum possible effort to perform your inspections and work. This is done using a simple hydraulic pump system that works as follows:
- Upon lifting the jack handle, oil is drawn into the pump cylinder.
- On lowering the handle, pressurised oil is pushed into the main cylinder, causing the main piston to raise.
- Repeated vertical pumping of the jack handle pushes further pressurised oil into the main cylinder, further raising the main piston.
- As the oil raises the piston, this causes the arm and saddle of the jack to extend, lifting the car.
This process turns lifting a tonne or more of automobile into a matter of a few easy handle pumps, hence why a jack lift is an invaluable piece of equipment for any garage. The trolley part simply means the jack is on (usually four) wheels, so you can use it where and when you ple
What is a trolley jack used for?
Lifting heavy vehicles, is the simple answer. Your trolley jack will give you the elevation you need to carry out essential work on your vehicle, be it a wheel change or adjustments to the brakes. Elevation levels differ between models, but typically you’ll find lifting ranges (i.e. the height to which you can lift your vehicle) between 100-500mm, with some models offering higher or lower.
Who are trolley jacks for? Well, virtually anyone who owns a car can find value in owning one. Head to your local service garage and you’ll likely see a number of jacks scattered about the place. Likewise, check in your average car enthusiast’s garage at home or their car boot and you’ll probably find one as well.
How much does a hydraulic trolley jack cost?
Although we can assure you that all our jacks represent exceptional value, that depends on what capacity of model you require. The lifting capacity of trolley jacks is wide ranging, with jacks available that are suitable for use with smaller cars through to models that are fit for use with trucks. Naturally, finding what sort of jack and capacity you require will be your biggest question, which brings us nice onto our next section.
Choosing a trolley jack – what size trolley jack do I need?
A common question a beginner might ask is why do vehicle jacks come in different sizes? The answer is very simple: bigger vehicles require bigger jacks.
Every jack is rated to a certain weight to help you select a suitable model for your lifting requirements. Because a jacked vehicle will only be lifted from one corner, you will only need a jack with a lifting capacity of around three quarters of your vehicle’s total weight. For example, a full-size family saloon will probably only need a jack with a 2-ton capacity to lift it. The best car jack for an SUV or 4x4, meanwhile, may need a capacity of at least 3 tons.
One of the most important factors to consider is how much your trolley jack can lift. As a rule, never put yourself at risk by using an under specified trolley jack to lift a vehicle that weighs more than an average car. Before you go any further with your potential purchase, check the weight of your car in your manufacturer’s guide or online to make sure the jack you’re looking at is going to be fit for purpose.

There are two further key considerations to bear in mind before purchasing:

- Jacking height – Look into how high you need to raise your vehicle. This is referred to as 'lifting range', and more often than not is measured in millimetres (mm). You can use the filters in the trolley jack category to refine your results to match the lifting capacity you require.
Trolley Jack Features Explained
The best trolley jack for lowered cars, low-profile jacks are designed to be used on vehicles with lower than average ground clearance, making them an essential for usage with many sports cars.
Designed to be lighter weight than their steel counterparts, aluminium jacks are an essential requirement for racing jacks and those who want maximum manoeuvrability.
High Lift / Long Reach
As it says on the tin, high lift jacks are the answer to how to jack your car up higher, giving you a greater lifting range for more specialist lifting applications, as well as greater flexibility. Long reach jacks lift vehicles with difficult to negotiate or deeper jacking points than your standard car.
This feature means the jack is designed to offer the minimum possible amount of lifts in the jacking process, courtesy of larger pistons or dual pistons. If you want super quick lifts with the minimum amount of effort, rocket lift trolley jacks are the pick for you.
Trolley Jack Kits & Extras
It’s worth mentioning that a trolley jack (or any kind of hydraulic jack) is designed to lift the vehicle only – not hold it for any significant amount of time. After you’ve lifted a vehicle to your required height, make sure to use good quality supports - such as our SGS axle stands - so you can work under your vehicle safely. Essentially - never work under a vehicle supported by a trolley jack alone.
Many of our trolley jacks are available with bundled axle stands for secure holding. If you’re going to be working under a car, axle stands are an essential accessory. See our video guide: “How To Lift Your Vehicle With A Trolley Jack & Axle Stands” to learn the best way to lift a vehicle to the point where it’s safe to be worked under. One more thing to note if you are considering extras – you’ll always get the very best value when you purchase an SGS bundle deal.
