If you are like me, the years have added a little bulk to your middle. The problem is you can't seem to slide under a car to change oil or do maintenance any more. These drive-on ramps are made of a space age foam technology and will support up to 3000 lbs. per pair, but are light enough at 30 lbs. to hang on the wall. They are 67" long, 10" tall and 14" wide.
