15,000 dump kit

Excellent quality and easy to install. It does take some welding and problem solving to install but this is a universal kit so it was expected. I am very satisfied and the kit works flawlessly. Also was notified before delivery so if I didn’t have a way to unload it they could send a truck with a lift gate.
