This heavy-duty lifting jack uses 2.25 cubic ft/min of compressed air at 100 PSI for efficient operation. Featuring precision-machined pumps, rams, and cylinders for long-lasting performance, it has a super-long 66” body for lifting vehicles with long overhangs. The foot-operated pump ensures quick lifting, while the handle-mounted locking control lever offers three positions for versatile under-car positioning. Automatic overload safety valves enhance safety during use.
