I have one of the aluminum racing jacks from HF. It's an OK jack for using on my street rod, but when I try to use it on a heavier car like my wifes Taho, or my full size truck, it requires a lot of effort to lift the vehicle.
There is a price to pay when you purchase a jack that has a fast lifting feature. Unless the jack has two seperate methods of lifting. The high dollar jacks I used to use at auto dealerships had a foot operated pump that quickly raised the head. Then you used the jack handle to raise the rest of the way.
