The kit provided everything needed. The most important item in the kit are the directions, as you have to almost take the dryer fully apart to do this. Unfortunately, I couldn't use the front vent on the side I wanted, had to use the one more to the rear because my model dryer had the motor in the way of the front vent. I'd already set up the outside vent to align with the front vent, so I needed two more elbows to hook up the dryer. If you want to save money you could just buy an elbow, two pieces of 4-inch pipe and some hose clamps and cut the pipe to length instead of using the kit, but the kit makes it easier.
