This Torin Combo Set includes a 2-ton trolley jack plus (2) 4000 pounds capacity supporting jack stands, in a convenient plastic blow mold case for easy storage. The rugged Torin Trolley Jack is strong and versatile for use with multiple vehicles. The jack is small in size, but big in performance. The jack's protective paint is resistant to oil, grease and dirt, while its steel frame provides maximum durability and strength when lifting large loads. The trolley jack features a 360 degree rotating saddle, positive locking safety release handle, and rear swivel casters for easy maneuvering and positioning. The integrated overload protection valve prevents you from lifting items weighing more than the jack's capacity, protecting the jack for longer life. The accompanying 2 heavy-duty steel ratchet action jack stands help to support loads raised. The stands are constructed of heavy duty steel and feature a locking pawl and tooth design for extra protection. Both the trolley jack and jack stands meet ASME PALD safety standards.
