It will hug and cradle axles up to 4 inch tubes. Should fit most Dana 60, Dana 70, and Dana 80 axles
It will likely work with most 20 ton bottle style jacks
It will also work with floor jacks, simply by locating it inside the jack cup
Smaller bottle style jack lifting pads will work, but there will be space between the jack and the tube and it will have to be centered, it’s ideal to have the lifting pad as close to 2 inches in diameter as possible for a better fit
