We have not run into any issues with Air Lift kit 57257 fitting on Dodge 1500 with a gooseneck hitch. The air spring kit will work with short beds. The air spring kit sits on the axle so it should not interfere with your hitch. You can view the instructions on our website which show where the kit mounts to verify there is nothing the the way.
Air Lift kit 57257 comes with everything needed to inflate the kit manually like you would a tire. They do not require on board air compressors, but they are a nice option. The smaller air compressors that can be used with this kit are Air Lift 25592 and 25850.
Feel free to call us at 1-800-358-4751 if you have any additional questions.
