Jack rating/ Harbor Freight jacks

[Whacker]

Does anyone have experience using the aluminum floor jacks from Harbor Freight with the M3?

The 1.5 ton jack is significantly cheaper than the 2 ton and up jacks. I have no idea how to calculate the load when most of the weight will be on the remaining 3 tires.

I'm looking to lift the car just enough to remove one wheel at a time so that I can place dynamat under the existing wheel well trim.

Thanks

Lifting a beam on one end requires half the force of lifting it from the middle. I'll guess that lifting a corner of a car is less than half. However, the jack point is not in the corner, and pictures of a jack use on one point show a good fraction of one side of the car being raised.

So I estimate half the weight, way under 1.5 tons

The car is so stiff I think you will find you do lift two tires at once, maybe not enough to remove both but enough I would use half the vehicle weight as above.

The 3 ton heavy duty low profile jack is much better. The 1.5 aluminum will work fine but it felt like the jack was struggling a little lifting a car that was almost 4k lbs. I have used it on a Lexus ISF which is ~3800lbs

Definitely get the biggest one practical. Small jacks really suck.

I used the 1.5 AL jack when i installed my hitch. It lifted the corner good enough but i was feeling like I wish I had a 2 ton jack

This thread made me think of the little jack that is bundled with cars that carry a spare. Compared to that thing the 1.5T jack from Harbor Freight is a monster.
