That is a good question. There is no database we can use to cross-reference and a lot of fifth wheel pin box manufacturers do not include the model on their label. The best way to find out is to have a dealership run your VIN. They should be able to tell you what model pin box the camper was originally equipped with.

If that fails, we have a chart that you can use to identify the pin box model. If you take a look at the link below you will find the measurement chart. You can take measurements of your current pin box and match them to the chart.

A very common OE pin box is the Lippert 1621 or 1621HD, which the Curt Air Ride 5th Wheel Pin Box # LC158778 is made to replace. So we definitely want to be 100% sure that you do have the 1621 Pin box currently.

If you find that your pin box is a different model, feel free to send me your findings and I am happy to make a recommendation.
