Hey Chris, that information is what we need to confirm.
I reached out to Lippert with that LCI number and the response was you have a 1621 with 15.5k weight capacity. Curt Flex Air 5th Wheel Pin Box # LC328492 is going to be a direct replacement and bolts right on.
This is a great choice because the Flex Air system drastically reduces chucking, absorbs road shock, and minimizes bounce. Instead of being solid it has an airbag and shock in it, so when you hit bumps, it smooths everything out a lot.
Is there somewhere you are excited to take the Cougar once this is installed?

I replaced the same pin box with the Curt Flex Air 5th Wheel Pin Box. It significantly smoothed out the ride. The chucking is gone and the camper rides much better. I pull a second trailer behind the fifth wheel and this pin box helped reduce the sway in the second trailer.
