A car can roll while propped onto Jackstands too. I use both ramps and Jackstands depending on what I am doing. As with jacking up ANY car and working under it, you should always use wheel chocks to block the tires and prevent the car from rolling. When my car is on the ramps, I have allot more clearence under it without worrying about hitting the jack stands and being cramped between the two stands. I have shaken, jumped, removed the transmission, ect..ect..ect..all while my car was on ramps and NOT once did it even budge. As with the "good quality" stands you suggested to buy, any "good quality" ramps will out perform them in safety. Granted you can't work on the wheels with ramps, but like I said, that's why I own both. BTW, I have had my car propped up on ramps (rear tires) and stands (front) so I could have enough clearence under the D to move around and work under it with no problems at all. Saftey is always key when working with any automobile. I've also had my car in hover mode too.....but hovering 4 feet off the ground, on a sloped driveway when I removed my chassis ;-) Steve --- In dmcnews@xxxx, jtrealty@xxxx wrote: > The ramps that I have seen are made from stamped sheet metal and spot > welded together.
