Sorry for the late review. Delivered but I can not install it for a long time. Because the auto center (mechanic) doesn't like to install it. This is a small amount of money. for her. And I need to buy a car air compressor for my car. My primary purpose in purchasing an air lift is not towing, but comfortable speed bump riding. Today I met a nice and friendly mechanic and finally installed my 60763 pneumatic lift. Thanks,
