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

Lippert Trailair air ride pin box air bag and 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.


Lippert Trailair air ride pin box air intake valve and inflation indicator

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.

Video Transcript for Lippert Components Fifth Wheel King Pin - Pin Box Upgrade - LC155943 Review

Today we're going to review part number LC155943. This is the Lippert TrailAir Air Ride Fifth Wheel Pin Box, designed to fit the Lippert 1116 Pin Boxes, and this has a 21,000-pound weight capacity. This Air Ride pin box will replace your standard pin box on your fifth wheel trailer, helps cushion your ride, improve your handling and it will even limit the strain that's on the truck and and the trailer itself. It does minimize chucking and it will also eliminate the bounce and jarring, also know as porpoising, when you get that effect on your trailer when you're towing. It has an internal air bag right here, helps absorb the road shock. You can see where the pivot point is right here, so it gives you a scissor-like motion and this allows that pin box to compress, compensating for the jarring and bouncing. You'll notice right here it has the built-in shock on the end here.

This insures that that pin box rebounds and keeps the air bag from breaking down. This internal air bag right here, this should be inflated after the pin box has been mounted on your trailer. Right up here is the air intake valve. Inflate the air bag until this outer cylinder on the shock right here will rise just above and fully expose this yellow inflation indicator sticker right here. You'll see the arrow is pointing up, so once you're above that, then it's fully inflated to where you want it. This is a black powder-coat finish on this, helps provide rust resistance.

It is a sturdy steel construction. The king pin connects to any fifth wheel trailer hitch. Right down here is your king ping. This is a bolt-on installation. There's no assembly required and this part is made in the USA.

The specs on this again, it's designed to replace the Lippert 1116 Fifth Wheel Pin Boxes. It does have a weight capacity of 21,000 pounds. When you're going to use this to replace the one you have, you do need to make sure you have the correct application, to make sure you have the Lippert 1116 Pin Box, you want to do some measurements. Basically, what those measurements would be is, you'll see you have the three rows and then what you're going to do is measure the horizontal distance between the center of the front row to the center of the rear row of holes. I put the marks at the centers just to make it easier to see. You can see it will be right at 8 3/4 inches.

That's the horizontal distance between the bolt pattern. The vertical distance between the holes, from the center to the center, is going to be right at 2 1/2 inches. The bolt hole diameter is 5/8-inch diameter. The other critical measurements are going to be from the center of the king pin, the king pin's right down here, so that center of that, I put a mark here, to the center of the front row of bolts and then the center of the king pin to the rear row of bolts. I've got this ruler here, we're going to try to get that measurement for you. If we go right there to about the center, you can see it's going to be 14 5/8 inches, and to the very rear it's going to be 23 1/4 inches. The last measurement I want to give you is the overall width. That's a critical measurement. On this one, let me try to rotate it here so we can get a good, there we go. The overall, outer edge to outer edge is going to be right at 12 1/2 inches. One last note, this TrailAir Air Ride Pin Box cannot be used with any of the gooseneck adapters, so you don't want to use this with any type of gooseneck adapters that are out there. That should do it for the review on part number LC155943, the Lippert TrailAir Air Ride Fifth Wheel Pin Box for the Lippert 1116 Pin Boxes, and has a 21,000-pound weight capacity. .

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

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 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

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

Review from a similar Lippert Components Trailair in Fifth Wheel King Pin


I love this AirRide by Trail-air. It provides an incredibly smooth ride on the road. You can adjust the amount of air for your ride, the Schrader valve is right on top of the unit and easy to access. My Trail air installed easily on my Forest River Sandpiper 372LOK mid bunk, especially with help from my Dad. This Trailair solved a big problem for me. I needed an extra couple of inches space between my 2018 Ford Super Duty DRW and the coach. My truck came with the Ford factory-installed Reese 27K hitch and I needed more clearance to allow the tailgate to drop without touching the coach. The kingpin on the Trailair sits at least 2” forward of the factory kingpin and provided that desperately needed space. It really makes for smooth and quiet ride ! etrailer folks were very helpful. The first unit was damaged by the freight company and when I notified them, etrailer sent another unit quickly. I will buy from etrailer whenever I can.. 646799

Your trailair should not be losing air that quickly. Changes in temperature can affect the pressure in the air bag just like it does with vehicle tires but only by a few psi. It sounds like you need a new tank valve for it part # LC156740

  • Cushioned Pin Box Recommendation to Replace Lippert 1116 on Raptor 5th Wheel Trailer
    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. Instead we have the Trailair Pin Box part # LC155943 which would be a great option that is cushioned and a confirmed fit.

    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.

Once the pin box is identified we can determine if there is an air ride pin box that will fit.

  • Difference Between Lippert 1716 and 1116 Pin Box
    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.

    You wouldn't need to remove any air from a Trailair like the part # LC155943 while storing it. Just be sure to check to make sure the pressure is correct when you go to tow again. The air system of this pin box is very heavy duty and lowering the pressure would not be needed.

  • 5th Wheel Pin Box Clearance on 2017 Ram 2500 with Rambox
    There is no way to add towing capacity to a vehicle. Tow weight ratings are determined by the auto maker for the specific complement of power train, suspension and frame in the vehicle. You can add items like transmission, engine oil or power steering coolers to reduce the operating temperatures of these systems - definitely a good thing that reduces thermal stress and resulting wear - but this does not make the truck's engine, transmission or frame any beefier so tow ratings will not change....

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.

You do not want the pin box to have a lower capacity than what the trailer is rated for. What you can do is use a different hitch with an air ride pin box instead of a Sidewinder.

    Trailer manufacturers typically don't give out parts breakdowns of their trailers, so the only way to find which specific pin box came with your trailer is to either find the ID tag on the pin box itself, contact the trailer manufacturer with your VIN, or measure the pin box using our help article, which I've attached for you. For a Lippert 1116, I recommend the Trailair Air Ride Pin Box, # LC155943. This model has a weight capacity of 21,000 lbs, which is more than enough to handle...

  • Improving Ride Quality When Towing a 5th Wheel Trailer
    You would get the most improved ride quality by replacing the pin box on your trailer. From the pictures it looks like you have a Lippert pin box based on the sticker on the front. I would just need to know the model number. If I had to guess I would say it is a 1116 model but I could be wrong. It looks like it uses 3 rows of bolts so it is likely a 1116 pin box. Whatever it is, let me know and I can recommend some air ride pin boxes that will fit if you have a pin box model that is...

  • Will a Trailair Pin Box Fit a 2010 Jayco Recon 39C 5th Wheel Toy Hauler
    Check for a sticker or plate on the pin box on your 2010 Jayco Recon 39C. If it indicates that the pin box is a Lippert 1116 then Trailair pin box # LC155943 will fit the trailer. If it indicates a different model pin box let me know. If you cannot find the pin box information on the pin box you can take some measurements on it to determine which one you have. I have included a link below to a help article that explains the measurements needed.

  • What is the Physical Weight of the Trailair Air Ride 5th Wheel Pin Box
    The Lippert Trailair Air Ride 5th Wheel Pin Box, # LC155943, for the Lippert 1116 model pin box has a shipping weight of 155 lbs. With the size and shape of this pin box, I recommend using both sons when installing on your trailer. If you have the availability of a tractor with a loader or fork truck, then either of these two vehicles will help out when installing the pin box. I have attached a video that shows installation of a similar Trailair Air Ride pin box on a trailer for you...

  • How to Reduce Chucking When Towing 2019 Keystone Fusion with Lippert 1116 Pin Box
    For the Lippert 1116 pin box replacement the best cushioned option is the Trailair part # LC155943. This system uses an air bag and shock to cushion and dampen the movement of the pin box which will do a great job smoothing out your ride quality. Another really big factor with fifth wheel chucking is the fifth wheel hitch jaw system. If you have a hitch that allows a lot of movement in the hitch jaws then that's where most of the chucking is coming from. You'd want a hitch that has...

  • Replacing Lippert 190737599 Pin Box On Trailer With Cushioned Trailair
    I spoke with Lippert and they said it appears you have the Lippert 1116 or Lippert 1716 wing set but were not able to narrow it down any further. That said, all you need to do to determine this yourself is measure from the forward-most bolt holes to the center of the kin pin. If you get around 20" or so then you have a Lippert 1716 but if you only get around 15" or so then you have a Lippert 1116. They actually both have the same bolt pattern so you could use either really. For replacement,...
