Trailair Air Ride 5th Wheel King Pin - Fabex 730, RBW 7019 - 21,000 lbs
The pin box worked out very well. You still feel the bumps but almost no chucking. My wife likes to sleep in the truck with her head against the head rest, but she could not do that with the old pin box. The only thing that I had to do with the new pin box was drill out the holes because the old pin box had bigger bolts.
