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 0719 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.
Ratings & Reviews
Air Ride Pinbox arrived on time and in excellent condition. It is a perfect fit and was an easy installation.
Thank You,

Hitch makes for a lot smoother ride than the factory one, I all so put air bags on the truck.
Rides very nice.
On installing the new hitch, there was a clearance problem. It was less than an quarter inch interference on the lower front part of the frame that the kingpin box bolts to that needed to be ground down for the pinbox to fit.
The next thing was the bag had a hole in it, so it needed to be aired up every day.
Got new one sent to me under warranty, witch was great.
But the video that showed how to replace it was for the wrong hitch.
I figured it out myself. Working good now.
Quick shipping in good communication
Exact fit replacement for cheap Keystone OEM part. Fit was so exact, I installed it by myself. Arrived earlier than expected. I hope this will reduce the chucking and smooth out the pull of a 16K RV trailer. I did have to purchase additional bolt sets from my local Home Depot (OEM was 12 sets, this is 18 sets 5/8-11 x 2in Grade 8 with flat and lock washers all torqued to 180 ft lbs).
This is a great unit on our Montana 34foot, we are in New Zealand and it arrived in great condition and the team at E Trailer are great
So far so good. It took me about 3 Hrs to R& R. Faster than I thought.
Have put around 10K miles on the hitch so far and it has performed well. An extra step in the pre-departure checklist to check the airbag pressure/ride height, but it is worth it as it greatly reduces the jarring from pot holes and abrupt changes in road surface. Installation was easy; perfect fit.
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.
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.
Smooths out the ride greatly, really pleased with so far. I removed the Air chuck and installed a tee with Gauge and air chuck makes it easy to monitor air pressure before traveling, one should note that these do bleed pressure down in few weeks that is pretty much normal for air bags of this type. I have a Dewalt cordless mini compressor and it works great to quickly & quietly pressurize before trip. I usually set my at 65 PSI
The pin box arrived in satisfactory condition. I have to install at this point. More to follow.
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.
We're so anxious to try out our new Curt TrailAir.
Installation went smoothly, it looks great.
We can hardly wait to experience the ride!
The pin box arrived on time and in perfect condition. The shipping company even off-loaded it into a covered area out of the weather for me.
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.
Freight co delivery estimated for Friday, arrived today. (Tuesday). Borrowed a tractor, dropped the old and lifted this monster into place. 12- 15/16 bolts (originally) 18 hole mount. Not sure if the height is correct for the bed, but will adjust it down if after the rubber bumper is inflated, if it doesn’t sit level. The bolt pattern was correct. better get help! From dropping the MFG lippert, to getting the thing lifted an bolts snugged up, about 45min. Will take a bit longer to attach the deadman switch and electrical box. Well crafted, definitely heavy. This should save my truck n RV from porpoising damage as I’m going over Bridges and bad roads.
A nice addition to our 5th wheel, helped smooth out the ride, especially on the roads up north
Looks great, way heavier than factory, easy change over. I did have to trim the corner of trailer frame to get room by the pivot pin in hitch. Looking forward to our trip north to see the difference
The pin box works perfectly.
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.
I'm pleased with the pin box. Put it on my 5th. wheel. The airbag gives us a better ride than any other pin box. Its a great product.
I just completed a 2800 mile trip after installing the Trail Air Air Ride pin box on my Solitude 5th wheel. I was able to install it myself from the bed of my pickup using a hydraulic bottle jack to lift it into position.
I previously made the same trip with the factory installed MORryde Cushioned Pin Box and the Trail Air provides a greatly improved ride. With the MORryde, I encountered several sections of concrete highway that set up a front-to-back oscillation which persisted across many miles. I didn't have that issue with the Trail Air.
I didn't order the Flex Air model that also included the flexible block because I was concerned the added height of that pin box would have been a problem. However, after installing the non-flex Trail Air I've found that the other one would have also worked out if I lowered my truck hitch an inch or two.
Also worth noting, this pin box is four inches shorter than the 1621 MORryde it replaced. However with a long bed truck I have no clearance issues and can still lower the tailgate when hitched up.
Well made and designed does exactly what I was looking for. A smoother ride for my truck and 5th wheel.
