Here is a simple DIY. Takes about 2 minutes and costs less than $2. Compare that to some of those fancy jack pads that cost upwards of $30. All you need is a hockey puck, hard "rubber feet" that can be purchased at a hardware store or ebay, and a long screw and electric drill.

Here are the raw materials:





Find the center of the puck and screw the feet into the puck. You will need an electric drill cause a screwdriver just ain't gonna do it!







Because the hockey puck is about 1" thick, you will need a low profile jack. The rubber "feet" goes into the jack hole, and the puck prevents any scratches as well as providing support. Once the car is up, you can put jack stands underneath the puck too.

 

clever ! ...but this should only be used until jack stands are placed directly under the frame ( not the pad) ....I would be nervous being under a car with all the lateral weight held by a few threads of a weak fastener screwed into a piece of plastic .

 

I've used pucks for years. Once you have weight on the puck it doesn't move at all. There is no lateral force to speak of. I am sure, as the OP intended, the part that is screwed into the puck merely helps with placement into the jack point. And yes, jack stands are always a must.
