Do not use the Trailair air ride pin box with any type of gooseneck adapter.
Because of the size of this item, it ships via truck freight.
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.
Air Bag Absorbs Road Shock
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.

I purchased this Lippert Air Ride hitch for my 40 foot Genesis Supreme trailer and wish I had bought it 2 years ago and installed it. What a difference is has made both in the trailer when towing as well as the difference in my truck while pulling it down the road. eTrailer had the best price and fast shipping. They as well helped me with verifying the right part number that works with my trailer. I purchase many parts and accessories from eTrailer and will continue to purchase from them in the future.819685
My hitch is working great! It has made a big difference in how well the trailer rides on my truck. No more harsh bumps when I drive over rough roads or poor bridge approaches. Awesome product!

Good looking product. Mounted it on a Montana 40ft 5th wheel. It arrived 2 weeks ahead of schedule. It was easy to install. I did have to grind the corners of the trailer frame bracket as the jaw hinge wouldn’t allow the bolt holes to line up. Once the corners were ground, everything lined up perfectly. It only took my son and I to pick up the pin box and once the first bolt was in, it was simple and easy to do the rest. There are 3 things to complain about. 1. The position of the air valve sucks. Really hard to get at. 2. The mark on the shock for proper inflation is not marked well. Had to get on hands and knees with a flashlight to actually see it. It was suppose to be bright yellow, it’s black, same as the shock. My 3rd complaint would be the fact that I had to drill 3 holes into the pin box to reattach the brake safety cable and the electrical wire box. The biggest positive thing is, is how much of a difference it has made in the ride quality for not only with the trailer but the truck as well. Soooo much smoother than the original pin box. Would I buy another one? You better believe I would. Wondering why I didn’t buy it sooner. Won’t have another 5th wheel without it.1137469
Have not did a road test yet but it’s installed. Way heavier than factory. I have talked to many that have this and like it. Helps reduce chucking back and forth movement. Nothing will be solve all if you are on a rough road you will feel it. No hitch will eliminate. Was fairly easy to install you will need help to lift. I used the tailgate on the truck and backed under and used blocking to get in place. I installed pretty much myself. My wife help some with aligning the bolts. 593929
Looks very good but I won't be installing the pin box until April we still have over 3 ft. of snow on the ground, Hope I can get the 5th wheel hooked up by April 9 ....1267438

This is my second trailair pin box and I just love them it takes all of the bouncing out of the truck in the camper and makes it a smooth ride. Shipping was great and product came packaged as good as possible. 846171
Can’t believe it can be so easy to back up with this hitch. Never go back to a standard hitch. I m sold forever but the capture plate for each hitch needs to be added to the hitch or at least give the part # for that specific item.1161651

by: Clifton 09/30/2021
This kingpin changes the feel of chucking and sudden impact loading (bridge abutments at 70 MPH). The energy is translated differently than a rigid pin…. It does not eliminate chucking or impact load, but it has eliminated the sense that my stiff sprung dually is going to bounce my trailer to death. Would not be without it!1168526
by: James M.10/01/2019
Excellent item! Works exactly as promised. The only issue I have, which is a small one, is that I have to pump up the doughnut before every trip because the air will leak out. Not a big deal because I have the compressor out to pump up the tires anyway. This pin box takes 98% of the chucking and side-to-side motion out of our fifth wheel. Makes for a lot less white knuckle driving, eases everyone's nerves, and we arrive at our destination without the near whiplash we used to have. If you are looking for a way to ease the ride, this is an excellent product to accomplish that goal.711395

Great product. Easy installation. With regular hitch, truck jarred really hard at bridge transitions. The air ride hitch took all the jarring out of the truck. Chevy 2500HD Duramax. 40’ fifth wheel. 703571

This 5th wheel pin works great smooth ride nothing moves in the trailer. After traveling 6000 miles last winter 579113

The TrailAir pin box is a good upgrade from an entry level unit. You have to learn what the ideal air pressure needs to be for your rig, ie, trial and error.
The TrailAir calms the fifth wheel trailer quit a lot going over bridge entries and over rough roads. It would be nice if they would install a tee on the air inlet port with the air add fitting and an air pressure gauge so that one could see the actual bladder air pressure anytime.320366

This was the very best upgrade we have done to our 5er. If you don't have one, get one! The difference and comfort is night and day. It projects the 5er and everything inside, the truck and just makes a world of difference! Can't say enough good things about it. 2007 Montana 3000RK.383478
The correct Trailair Air Ride 5th Wheel Pin Box for a 2006 Keystone Montana 3500RL is part # LC155943 which will be a direct bolt-on fit without any drilling required therefore it would indeed line up with the existing bolt holes on the trailer wings. The Keystone Montana 3500RL uses a Lippert 1116 Pin Box based on my research. view full answer...
The mounting hole to pin measurements are the same on all of the 1116 pin boxes including the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 part # LC155943. view full answer...
In order to use the TrailAir Air Ride # LC155943 with your SuperGlide hitch you will need to purchase a capture plate for it. We do not currently carry PullRite products so we don't have the capture plate that you will need available. I was able to find out that in order to use the SuperGlide hitch with this pin box you will need capture plate 331758. view full answer...
I contacted Lippert on your behalf. Your current LCI 1116 measures 17-7/16" from the bottom of pin to the top of pin box mounting. The Trailair Air Ride 5th Wheel Pin Box # LC155943 measures13-1/2 plus the pin at 3-3/8" or 16-7/8" making about 1/2" in height reduction.

The air bag suspension enhancement you have installed in your 2016 Ford F-250 does not affect the choice of a cushioned pin box at all. A cushioned pin box like the Trailair you mentioned and air bag vehicle suspension enhancement work really great together actually.
The Trailair pin box part # LC155943 that you referenced would be exactly what I would recommend. This will give you a much smoother ride and is also perfectly compatible with your Curt A16 fifth wheel hitch as well!

The lower bolt of the air bag need to attach through the hole that you can see in your picture. So you'd need to pull off that nut and push the stud through that hold and then reattach the nut on the other side. view full answer...
I would be happy to help you find out if the Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs # LC155943 you were looking at will fit your 2015 Keystone Fuzion 5th Wheel Toy Hauler, but unfortunately we do not have a break down of which pin box was used on a specific trailer.
The # LC155943 is confirmed to replace the Lippert 1116 Pin boxes, so if that is what your trailer uses this would be the correct fit.

There is not a cross reference for travel trailers that would identify your pin box brand or model. If you need repair parts for your existing pin box, you would have to call Keystone/Montana with your trailer VIN and Year to see if they can tell you.

Your Road Armor pin box has an 1116 bolt pattern so the FlexAir pin boxes will not fit. The Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000lbs Item # LC155943 will though. The Air Ride pin box utilizes an air bag to reduce chucking and improve handling just like the FlexAir. view full answer...
Your 2021 Keystone Montana 3231CK uses an 1116 pin box with a 19K capacity. For this application use the Trailair Air Ride 5th Wheel Pin Box part # LC155943. This offers a slightly higher capacity but will be ideal for your rig.
It will mount using your existing hardware and it is generally a good idea to have some help available to get the old one out and the new one up and in position.

The Trailair Air Ride 5th Wheel Pin Box part # LC155943 is my recommendation for a cushioned pin box for a Keystone Montana with Lippert 1116 Pin Box. The Trailair has both an integrated air bag and shock absorber so it will do the most for eliminating bouncing and jarring. It's also made here in the USA. view full answer...
If the bag is starting to crack, then it is time to replace it. We do not want you on the road with a cracked bag as that could damage your equipment or put someone in danger if it goes on the highway. If your bag is leaking, it is also time to change the bag. To know if it's leaking, set the bag up like you normally do and then check pressures periodically as you drive around.
The starting pressure should be about 80 to 90 psi, with the pressure increased according to the ride height... view full answer...
The Lippert Trailair Air Ride 5th Wheel Pin Box # LC155943 is a direct bolt-on replacement for the Lippert 1116 OEM pin box. The air-cushioned Trailair provides a smoother ride by reducing chucking and jarring and it comes fully assembled. It is rated for 21K.
Please note that the Trailair is not to be used with any type of gooseneck adapter. view full answer...
You can check the shock by disconnecting one end and manually applying pressure. If you can easily compress it, then it probably needs to be replaced with # LC177223.
A Trailair Air Ride 5th wheel pin box like # LC155943 has both a rubber air spring and a shock absorber to ensure the air bag rebounds after compressing.
I suggest you inflate the bag to the level required to raise the shock to the recommend height; this is noted on the shock tube by a yellow sticker with arrows. Unless... view full answer...
There is not one specific recommended pressure for the air bag in the Trailair Air Ride 5th Wheel Pin Box # LC155943. The bag's pressure can range from 20 to 120 psi depending on your situation. After some miles you'll likely find the sweet spot for your trailer.
Once the pin box is installed, hitch the trailer to the tow vehicle on level ground. There is a sticker on the front of the shock absorber on the pin box. You should inflate the air bag until the bottom lip of the top shroud on... view full answer...
The pin box you have on your 2016 Raptor by Keystone is the Lippert 1116. On the sticker on the pin box there should be that series of numbers listed. We have had several other people with your trailer email us looking for the same thing and they told us they had the 1116 pin box.
For an air-ride pin box with a 21k capacity you would want the Trailair Air Ride 5th Wheel Pin Box # LC155943 which will give you a much smoother ride quality. view full answer...
The airline and more specifically the valve on the Trailair pin box # LC155943 is a Schrader valve. This is the same type of valve used in the valve stems on your tires. Air will not leak out rapidly. Changes in temperature can affect the pressure in the air bag just like it does with vehicle tires but only by a few psi. view full answer...
Basically the biggest difference between a Lippert 1116 and a Lippert 1716 is that the 1716 extends out further than the 1116. The 1716 is considered a long pin box whereas the 1116 is considered a medium length. The length difference will be 5-3/4 inches between the two. view full answer...
To determine if the Trailair Air Ride 5th Wheel King Pin # LC155943 will fit your 2012 Volts Toy Hauler model 3005 you will need to first determine what pin box you have on your trailer. There should be a plate or sticker on the pin box with this information.

To install a Trail-Air like the part # LC155943 on a trailer is not an overly difficult task. Virtually any shop could do it as it basically only requires removing the old pin box and then raising the new one in place and bolting it in place.

There should be a sticker or plate on the pin box itself that lists the manufacturer and model of the pin box. If it is not present then there are some measurements you can take to determine the model of the pin box. I have included a link that explains these measurements for you.

We do have cushioned pin boxes that will fit and work well in place of a Lippert 1116 but the Tri-Glide was phased out a while ago and no longer available.
