I needed something that would fit under the front and rear of my C6 Corvette. I still had to drive onto a 2x12" to get extra clearance in the front. The jack will fit under rear differential without additional help. Have only used the jack a couple of times so far, but it has worked very well. Lifts half the car with no problem. Easy to control the lift and release speeds with the control valves. The fittings which came with it attached to my compressor with no issues. It easily raised the car enough to get jack stands under both ends. I did copy a previous post and lubed the internal telescoping cylinders, although they appeared to be adequately greased already. I did not experience the jerky lift or release that someone reported.Jacking a Corvette is still a chore, but this jack makes it much easier than any other that I've tried. If it holds up it will have been a great purchase.
