The Powerbuilt U-Jack saves you time and hassle doing your own service and repairs like brake jobs, tire rotations, wheel swaps, and more. It eliminates the hassle of placing a jack stand at a factory-approved lift point on your car or truck. The secret? A patented saddle with a slot in it that fits the mast saddle of pretty much any jack stand on the market. Simply jack up your vehicle with the U-Jack, place a jack stand in the saddle slot, then lower and remove the U-Jack. It's that simple!
