Experience smooth, stable towing with your fifth-wheel trailer by replacing your ordinary pin box with an air-ride-equipped model. The scissoring action of the coupler allows the interior air bag to absorb road shock so that you won't feel it.

Notes:
Eliminate the bounce from your ride with the Trailair air ride coupler. The unique scissoring action of the pin box ensures that road shock is absorbed, preventing the harsh, rigid ride that you typically encounter while towing your fifth-wheel trailer. Not only does this improve your overall towing experience, but it also helps maintain a sound, well-functioning system. Less bounce and jarring means less stress on your truck, trailer and hitch.
When you encounter uneven terrain on your trip or hit a pothole on the highway, the Trailair pin box compresses, transferring the road shock to its internal air bag. A built-in air spring ensures that this compression occurs in a controlled fashion so that the air bag doesn't burst. It also causes the pin box to appropriately rebound, positioning it so that it's ready for the next bump in the road.

Best thing I ever bought for my rv
The product was great. The service was great. The freight company left a lot to be desired.
It took about a month to get here but we are so glad it did. Thank y’all so much!
This really helped with the chucking I was experiencing.
I just got the pin box, so I don't have it installed yet. It seems very well built. I wish it had a removable eye in the top so I could lift it with the crane that I have in the bed of my truck. No complaints though. Can't wait to try it out.
This pin box smoothes out the ride in the truck. No more chucking. No noise at all.
It makes all the difference on rough roads. It eliminated a lot of the bounce. It was a wise investment.
