TL;DR
- The Arcan ALJ3T is a 3-ton aluminum hydraulic service jack, much lighter than an all-steel jack of the same rating (Arcan, 2013).
- Reviewers praise its quick-rise action, which reaches the lift point in fewer pumps (The Tested Hub, 2026).
- Arcan's manual says never to work under a vehicle held only by the jack, and to lower the load onto rated jack stands (Arcan, 2013).
- Arcan warns never to use brake fluid, alcohol or transmission oil in the jack, because they damage the seals (Arcan, 2013).
- Aluminum is less tolerant of drops and heavy shop abuse than steel, so the ALJ3T suits home garages best.

How we reviewed this product: we studied Arcan's user manual, retailer listings and owner feedback, and compared the ALJ3T with steel and hybrid floor jacks. We did not run our own load tests.
What Is the Arcan ALJ3T Floor Jack?
The Arcan ALJ3T is a 3-ton hydraulic floor jack built mainly from aluminum. It lifts one end or corner of a car, crossover or light SUV so you can place jack stands underneath (Arcan, 2013).
Arcan is a garage tool brand owned by PowerStation, LLC (Arcan, 2013). The ALJ3T is one of its best-known jacks for home mechanics.
A floor jack is the first tool you need for any wheel-off brake job, because the factory scissor jack is only meant for roadside tire changes.
Why an Aluminum Floor Jack?
An aluminum floor jack is much lighter than a steel jack with the same lifting rating, so it is easier to carry, roll and position. That matters if you work in a driveway or move the jack between cars.
The trade-off is toughness. A buying guide notes that aluminum is less durable than steel under repeated heavy use or accidental drops (The Tested Hub, 2026).
Arcan also sells hybrid jacks that mix aluminum and steel. One hybrid 3-ton model weighs 58.3 lb and lifts from 4 to 18.6 inches (Costco, 2026), which shows how designs vary, so always check the exact model's specs.
How a Hydraulic Floor Jack Works
A hydraulic floor jack uses a small pump piston to push oil into a larger lifting cylinder. Because the lifting cylinder is bigger, a small push on the handle creates a large lifting force.
- Each pump of the handle pushes a little oil into the lifting cylinder.
- The cylinder pushes the lifting arm and saddle up toward the vehicle.
- A check valve stops the oil flowing back, so the load stays up.
- Turning the handle opens a release valve, letting the oil flow back slowly and the load come down.
A simple comparison is a syringe pushing water into a balloon. Small pushes add up until the balloon is big enough to lift something heavy.
Arcan's Safety Rules for the ALJ3T
Arcan's manual lists clear safety rules. Following them is the difference between a safe brake job and a dangerous one (Arcan, 2013).
- Inspect the jack before each use.
- Never lift more than the rated capacity.
- Never move or roll the vehicle while it is on the jack.
- Use only adapters approved or supplied by Arcan.
- Place jack stands of suitable capacity at the vehicle maker's support points before working.
- Lower the load slowly and carefully.
- Clean water, snow, sand or grit off the jack before use.
How to Lift a Car Safely With the Arcan ALJ3T
To lift a car safely, chock the wheels, jack at the maker's lifting point, place jack stands and lower the car onto them before you start work. Follow these steps.
- Park on level concrete, set the parking brake and chock the wheels at the other end of the car.
- Find the jacking point in your owner's manual, usually a reinforced frame point or pinch weld.
- Roll the jack under the car and center the saddle under the jacking point.
- Close the release valve and pump the handle until the tire is just off the ground.
- Place a rated jack stand at the maker's support point, such as the Big Red 3-ton stands.
- Turn the handle very slowly to lower the car onto the stand, then check the car is stable.
- Leave the jack lightly in place as a backup if there is room.
How to Look After the Arcan ALJ3T
Keep the ALJ3T working well by bleeding air after shipping, topping up with the right oil and storing it with the arm fully lowered.
- Arcan notes that air can enter the hydraulic system during shipping; if pumping feels spongy, follow the manual's air-bleeding steps (Arcan, 2013).
- Top up only with hydraulic jack oil, never brake fluid, alcohol or transmission oil (Arcan, 2013).
- Store the jack with the arm lowered to protect the ram from rust.
- Wipe grit off the saddle and wheels after each use.
Pros and Cons of the Arcan ALJ3T
The main strength of the Arcan ALJ3T is its light aluminum build with a 3-ton rating and quick lift, and the main limit is that aluminum handles drops and shop abuse less well than steel.
Pros
- It is much easier to carry than an all-steel 3-ton jack.
- The quick-rise action reaches the car in fewer pumps.
- Its 3-ton rating covers most cars, crossovers and light SUVs.
- The manual gives clear safety and maintenance steps.
Cons
- Aluminum is less tolerant of drops than steel.
- It may not lift tall trucks high enough; check the listing.
- Very low cars may need a low-profile saddle position or ramps first.
Common Floor Jack Problems and How to Fix Them
Most floor jack problems come from air in the hydraulics, low oil or a dirty release valve.
| Problem | Likely cause | Solution |
|---|---|---|
| Pumping feels spongy | Air in the hydraulic system | Bleed the air as shown in the manual |
| Jack will not lift | Release valve open or low oil | Close the valve fully and check the oil level |
| Load sinks slowly | Worn seals or dirty valve | Have the jack serviced; never work under it |
| Jack lowers too fast | Release valve opened too far | Turn the handle very slowly when lowering |
