Enjoy smooth, stable towing with your fifth-wheel trailer by replacing your ordinary pin box with this air-ride-equipped model. An internal air bag and built-in strut absorb road shock so that you won't feel it. Replaces Lippert 1116 pin boxes.

Notes:
Getting there is half the fun, right? Not if you're being bumped, jerked, jammed, and pushed around from the chucking and road shock that occurs as you tow your fifth-wheel trailer or RV. And imagine the costly wear and tear on your trailer as it endures that rocky ride.
Put the fun back into your trip and ease the stress on your trailer by replacing your factory pin box with the Trailair air ride pin box. The internal air bag and built-in shock work together to cushion your ride, improve handling, and limit strain on both your truck and your trailer.
Standard pin boxes without any type of shock absorption transfer road shock to your trailer, resulting in potential damage to the trailer and an overall bumpy ride. But the Trailair air ride pin box absorbs shock and cushions your ride as you pull your fifth-wheel trailer. When you encounter uneven terrain on your trip or hit a pothole on the highway, the Trailair pin box compresses vertically, similar to how a pair of scissor blades closes in on each other. This compression transfers the road shock and vibrations to the internal air bag, saving your fifth-wheel hitch, trailer, or tow vehicle frame from enduring a rocky ride.
A built-in strut, or shock, controls the Trailair's compression so that the internal air bag doesn't burst. The strut also causes the pin box to appropriately rebound without any bounce, and positions it to be ready for the next bump in the road.
Simple Setup and Installation
First, simply remove your existing Lippert 1116 pin box from your trailer. The Trailair uses the same bolts that held on your original pin box so no additional hardware is required for installation. Plus, the Trailair pin box comes out of the box ready to be put on your trailer, so no assembly is needed. Because the Trailair is quite heavy, you should put it on an elevated surface or have a friend help you support its weight during installation.
The internal air bag should be inflated after the pin box has been mounted on your trailer. Using the air intake valve, inflate the air bag until the outer cylinder of the shock rises high enough to fully expose the yellow inflation indicator sticker.

Good packaging and received quickly.
GREAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The pin box works perfectly.
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!
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.
There was a mix up with the order but once it got straighten out,they reshipped another one.I told them that I needed it by Friday,I don't know how but it made.it I would use this company again in the future.
Thanks
There is a smoother ride now, but it didn't eliminate the push/pull effect completely while going down the highway as I was told by another it would do. All in all I am glad I bought it.
Worked out great on my 2011 Cameo, wouldn't own another 5th wheel with one.
love it worked so good, love Etrailer also great company
Made a huge difference in the way to 5er tows now. Less bouncing and chucking, the coffee maker on the counter stays in place and things inside don’t move around anymore. It cut down on the stress to the 5er more than I expected, I can feel the difference in the driver seat also so it has been a very nice upgrade.
Really is a smooth ride after adding the air cushion pin box. Makes pulling a pleasure.
We needed a longer pin box and one that would give a better ride. Spoke with representative from etrailer who was very helpful. It has made a huge difference in ride and maneuverability.
The hitch is on a 2011 28' Coleman 5th, pulled by a '98 Dodge Ram 3500 dually. The ride is greatly improved. No more chucking and bouncing. I would have given 5 stars but the airbag won't hold air overnight.
Best ever. So glad I ordered this..easy to install and was just what I needed for our new 5th wheel toy hauler.
Works great I can watch my golf cart trailer behind my fifth wheel
Great phone assist prior to ordering as always and product was just as described. Shipping was a little hard to track as UPS advised the unit was sitting in our town but unable to locate for 5 days. E-Trailer is always awesome to work with. Thanks to all your staff.
I think that this is just what the doctor ordered. I have not installed it yet, but this looks very much like what I need for my trailer!
The Trailair pin box is a great product.
I installed it before a 700 mile trip and it does what it is intended to do. Etrailer was very helpful in selecting the correct pin box for my trailer.
Thank you.
The trail air makes trailer ride so much better,very little chucking and a smoother ride it is very heavy but with a little help it was installed in no time. Thank you to etrailer for the fast shipping and great price.

Using this Trailair Air Ride 5th Wheel Pin Box to replace the OEM standard (rigid) pinbox on my Montana unit allowed me to both lower the pin and shorten the pin box to mate up perfectly with my Curt hitch in a longbed GMC 3500. The ride greatly improved. I do wish the air valve had a 45 or 90 degree turn as it can be very difficult to get most air chucks onto the valve. There is not much clearance between the top of the valve and the underside of the the trailer, and the unit does require frequent refilling. If not for that difficulty I would give five stars.
The Trailair fits the bill for us. We have a Beacon 5th wheel and sitting with the trailer level the pin box wings sit below the bed side rails. With the original Rotaflex or Reese goose box the wings would hit the side rails in a turn more than 50 degrees. With the shorter Trailair the wings don’t hit. We are using it with an Andersen Ultimate with the coupler forward of the pin.
Do you have a question about this 5th Wheel Pin Box?
