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.

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!

Havent used it yet, but M19 pin box is well made. As usual, etrailer shipped it quick and it arrived with zero defects. Ill update after first use

Product works as advertised, but didnt reduce the chucking we get as much as Id hoped it would. Bottom line, it does reduce road stress over all and Id buy it again
by: Walt N12/05/2023
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.
by: John 01/24/2024
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.
by: Hoss09/06/2022
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).

Makes a world of difference in towing comfort. Jarring is minimized at stops and smooths out the tow on rough roads.

@Hoss We're glad to hear that your # LC155943 Trail Air replacement pin box has improved your towing experience!!

Pinbox came 3 days earlier then expected. It was packaged well, no damage. I unbolted the original inbox and 2 friends lifted the Curt into place and I bolted it back into place. Took about 15 minutes. Now for the real test when we head back up to the north for the Summer in Montana.

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.

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!
by: David08/28/2021
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.
by: Rich12/29/2018
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.
by: Chris07/20/2020
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.
by: Jerry02/17/2023
We bought a new fifth wheel right after we bought the pen box and we were going to have it put on our new fifth wheel but the bolt holes didn’t match up. Therefore it was never used and has been sitting on our RV LOT ever since. We couldn’t rate because never used it but only way it would let us submit our comments

Congrats on the new RV! I suspect what happened is that the new RV does not have a Lippert 1116 5th-wheel pin box. This does mean that the mounting bolt pattern will be different which you discovered. I think that your best bet will be to sell the pin box. If you can tell me the pin box number of the pin box that is on your new RV I can tell you if there is a Trail Air pin box that will work.
by: Philip 05/12/2023
Tremendous difference in the way the 5th wheel and pickup rides after installation. Well worth the money. Fast shipping from etrailer.
by: Gary 01/21/2023
I think the air takes some of the roughness out of the ride. It seems better than my previous pin box. I believe however that the air chambers lose air over time and I have had to add air before some of my trips. I don’t think air chambers need to be replaced but monitored for air pressure.
by: Jack 08/25/2021
Air Ride Pinbox arrived on time and in excellent condition. It is a perfect fit and was an easy installation.
Thank You,

I towed our Keystone Raptor about five thousand miles with the original pin box before I decided to try to smooth out the ride so purchased and installed the Trailair Air Ride 5th wheel pin box. I have since towed it approximately Six thousand miles and We are completely satisfied.
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.
by: indiantom11/28/2016
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.
by: Rich 09/13/2019
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.

Not the improvement I was expecting. Wish I would have got a gen-Y hitch
by: Charles 09/24/2021
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.
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!
by: Andrew 02/14/2021
Delivery was quick and product was as advertised. I called customer support (Danielle H) and she was extremely helpful and knowledgeable. Danielle helped me make sure I ordered the proper Trailair king pin based on dimensions of my current 5th wheel.

This 5th wheel pin works great smooth ride nothing moves in the trailer. After traveling 6000 miles last winter
by: Michael03/01/2022
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 ....
by: Migrant Pilots05/22/2017
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.
by: Roger M.12/22/2016
Had problems with air leaking. Found the valve stem was not tight.
Don't feel that it helped the ride characteristics very much.

- Determining The Pin Box Bolt Pattern On A 2013 Keystone Raptor Toy HaulerDimensions on most pin boxes are not the same, with the most important differential being the bolt pattern. Your pin box should have sticker on it either on the side or front that will have some serial numbers on it that we can use to identify the pin box. If yours doesn't have a sticker then you can use the guide I've attached below and take some measurements to determine the bolt pattern.

- Replacement Pin Box Recommendation For Lippert 1116The Trailair Flex Air 5th Wheel Pin Box, part # LC328492, is designed to replace the 1621 pin box, but is not designed to replace the Lippert 1116. The replacement pin box we offer that is a direct replacement for the Lippert 1116 is the Ultra-Fab Trailair Air Ride 5th Wheel Pin Box, part # LC155943.
