The Black Jack 2-1/2 Ton Trolley Jack is a must-have accessory for all automobile owners. Change tires and oil or perform other vehicle maintenance with the help of the Black Jack 2.5-Ton Hydraulic Trolley Jack. With its heavy-duty steel construction, it has the strength to lift a wide range of makes and models. The saddle is shaped to grip the underside and remain securely in place while you pump the handle. It lifts up to a maximum of 14.17" to provide you with clearance and rolls easily along the garage floor on front and rear wheels. A twist-valve release lets the car down slowly and safely, while the over-pump bypass valve lets off excess pressure. The lifting handle also detaches for transport and storage. Low Profile design works for most vehicles, including chassis with 4" ground clearance.
