We developed this inexpensive adapter to allow jacking up either the front control arm or rear spring mount for changing a tire or working on the brakes. It locks onto the top of the $27.88 Walmart HyperTough two ton trolley jack which is also sold under the Torin or Amazon Basics name and many others. It is shown jacking up the Gen 3 Prius v but will work with most other cars. Very little lifting distance is needed to lift the car to get the tire to clear the ground.
