3-Ton Aluminum Floor Jack

The one you carry. An aluminum body brings the whole jack down to about 57 lb, and a 3.3 inch saddle gets under a car that a steel jack has to be lifted onto ramps to reach.

Why this one

What this model does that the other four do not.

  • Light enough to carry

    Aluminum takes roughly 25 lb out of a comparable steel jack. That is the difference between wheeling it around one bay and putting it in the trunk for a track weekend.

  • Gets under a low car

    A 3.3 inch saddle clears the front lip on most lowered cars without ramps, wood blocks or a run-up.

  • Aluminum is not weaker here

    The lift arm and the pump assembly are steel. The aluminum is in the side panels, where the load path does not run.

Questions about this jack

Short answers on fit, capacity and safe use.

Is an aluminum jack strong enough for 3 tons?

The rating is set by the hydraulic cylinder and the steel lift arm, not by the side panels. What aluminum changes is the weight you carry and the price, not the capacity.

Will it fit under my lowered car?

At 3.3 inches it clears most factory-low cars and mild drops. If your car sits under about 3.5 inches at the pinch weld, measure before ordering.

Can I leave it in the car?

Yes, and that is the point of this model. At about 57 lb it lifts into a trunk without help, which the steel models do not.

Before the first lift: a floor jack raises the vehicle, jack stands hold it. Never put any part of your body under a vehicle resting on the jack alone.
