I have one and love it. Princess Auto has them on sale quite often. They adjust for different tire sizes. I have mine maxed out to slip over my 37's which are 14.50" wide. Makes it so much easier to work on the motor, especially if you are lifted.
In fact, here is the one from PA. Not currently on sale but will probably be easier and cheaper to get than from Northern.
