The lightweight racing jack is made of aviation aluminum billet, which is highly durable. Lifting your weight swiftly in just 3-1/2 pumps is made possible by an aluminum handle with knurls that guarantee a solid grip. The racing jack also has a small form that makes it easy to store and transport, as well as a universal joint release mechanism for precise, smooth lowering. To make lightning-fast pit stops, just half a turn is required to release the racing jack!
