How to Determine What Pin Box is on a Trailer to Determine Which Cushioned Pin Box is Fits  


How do I know what king pin box I have now,no tag on front. The side bracket has a tag LC128-028745 on it. I have a 2008 KZ Durango 5th wheel trailer. Want to get a lipper air ride unit. Price and part number please.

I can easily help you determine which pin box you have on your trailer. Since it is a Lippert I know we have a cushioned pin box that would work for it. But you will need to take a few measurements to know for sure. If you check out the link I attached you will see exactly how to measure your pin box to determine which you have and what cushioned pin box we offer that would fit it.

The part # LC158778 would be the correct pin box to use if you have a Lippert 1621 pin box which is a very popular pin box. Most likely this is what you will end up needing. I attached an install video for you to check out as well.
