When it comes to a replacement or an upgrade pin box you'll need to determine the pin box that you currently have. You will need to find the pin box's manufacturer name along with the pin box number which is typically located on a sticker on the side of the pin box or king pin itself.

If you are having trouble finding the number you will have to measure the pin box I will put a link below showing how to measure your pin box. Unfortunately there isn't a database that allows us to see what pin box a trailer has without doing some research.

The Lippert 1621SHD 5th Wheel Pin Box # LC1387882 will work for the Lippert 1621SHD pin box. When you find out the information I asked for please reach back out to me and I will provide you with the correct part numbers that you need.
