Lippert Components Fifth Wheel King Pin - LC155943

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.

    • Eliminates bounce and jarring

  • 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

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. .

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

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

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

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. 272841

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

Great product to tame the 5er bucking down the highway on those concrete seams. Ride is much smoother and I'm sure it is reducing the wear going down the highway on both the trailer and the truck. 526032

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

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


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. 615141

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


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. 498680

  • Cushioned and Extended Pin Box Replacement for Lippert 1116
  • The only cushioned/extended pin box we have that will replace the Lippert 1116 pin box and provide more than 23-1/4" from the rear most bolt holes to the center line of the kingpin is the 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder part # RP61412.

  • How to Determine Fifth Wheel Pin Box Model
  • If you are unable to contact your trailer's manufacturer with your VIN to find the factory pin box model number there are some steps you can take which will allow you to determine what pin box model you have so you can purchase a new FlexAir. To do this you will need to follow the steps in the linked help article, which I will go over with you. Start by selecting your pin box style like in the accompanying photo (which you will also find in the help article). You will then need to use...

  • Do Trail Air Pin Boxes have the Same Dimensions as the Pin Boxes they Replace
  • Replacement pin boxes such as # LC155943 aren't exactly the same as the stock pin boxes they replace. But they are really close because they have to be. I am confident you won't run into any issues with the ride being off level. Like you said the pin box can be mounted higher or lower on the trailer's mounting wings. The 5th wheel hitches, # BWRVK3300 for long beds or # BWRVK3370 for short beds, for your 2018 Ford F-350 are also height adjustable. I have included some links to all 3...

The Flex Air system is only compatible with the 1621 Pin Box. The Trailair Air Ride 5th Wheel Pin Box - Lippert 1116 - 21,000 lbs, # LC155943, you mentioned is the air ride equivalent in style and function for your 1116 pin box.

The 1116 is considered a medium length pin box and is about 7 inches shorter in length horizontally. The 1716 Demco Glide Ride will bolt up and could work well but it's going to be a bit longer.

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

  • Is Andersen Ultimate Adapter with Mor/Ryde Pin Box on Fifth Wheel Trailer
  • The MOR/ryde pin box is compatible with the Andersen Ultimate Connection 5th Wheel Trailer Hitch System Adapter part # AM3200 and will not need to be changed out. Vertical chucking would be reduced with that pin box and the Andersen Ultimate. From previous customers we know that the Lippert 1116 is the style of pin box you have on your Montana High Country 345rl so for a cushioned pin box that we carry the Trailair Pin Box part # LC155943 would be our best option as we do not carry the...

  • Trailair Air Ride King Pin Replacement for a Lippert 1116 Pin Box on a 2008 Montana 5th Wheel
  • The Trailair Air Ride King Pin, # LC155943, is an air ride replacement pin box option for your Lippert 1116 pin box on your 2008 Montana Fifth Wheel. We also carry the more economical Fifth Airborne Premium Fifth Wheel Coupler, # 5AB-S500-700, as a replacement for your pin box. Both pin boxes are rated for 21,000 lbs. You should check your trailer weight capacity before purchasing a replacement pin box.

  • Adjusting Air Bag Pressure in Trailair Air Ride 5th Wheel Pin Box LC155943
  • 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...

  • Do TrailAir Pin Boxes Require Lowering Pressure During Storage
  • 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. As with most air bag support devices you want to always have at least the minimum pressure rating in the bag at all times. So no lower than 20 psi. From the picture you submitted you have a Lippert 1116 pin...

  • Pin Box Replacement Recommendation for a Lippert 1116 to Reduce Chucking
  • For a cushioned pin box to replace your Lippert 1116 pin box I would recommend the Trailair Glide part # LC155943 as it has been confirmed as replacement fit. Integrated steel rollers allow the bottom jaw to glide, reducing the push and pull that is typical in fifth-wheel towing. The internal air bag cuts down on bounce by absorbing road shock. The Trailair Tri-Glide works to defeat this troublesome occurrence by incorporating steel rods into the bottom of the pin box. These three...

  • 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 Ride Pin Box Replacement for OEM Pin Box on a 2010 Keystone Raptor

  • How to Choose the Correct Trailair Pin Box for Keystone Laredo
  • In order to choose the correct Trailair Pin Box for your Keystone Laredo you will need to know the manufacturer and model number of your current pin box, which should be on a sticker or stamp somewhere on the pin box itself. If you cannot find it, simply call the trailer manufacturer with your VIN and they should be able to tell you what pin box it is. You will be able to select the correct replacement from there. For example, the Trailair # LC155943 is designed to replace Lippert 1116...

  • Can an Air-Ride Pin Box Be Used With a Gooseneck to Fifth Wheel Hitch Adapter
  • It's not recommended to use a gooseneck adapter with an air ride pin box. The air ride feature allows front to back and side to side movement to cushion shock. This movement would damage the pin box or the adapter. The Reese Goosebox would be an excellent option for you. The Goosebox is an air ride adapter that would replace your existing pin box and would allow you to hitch directly to the gooseneck ball. The Goosebox is only compatible with certain pin box models. The manufacturer...

  • Air-Ride Cushioned Pin Box Recommendation for a 2016 Keystone Raptor Fifth Wheel
  • 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.

  • Replacement Pin Box Compatible With 2014 Keystone Carbon 327
  • There often is a pin box number printed on your factory pin box. That number is normally found on a sticker directly on the pin box itself. If you cannot find this number, there is an easy way to measure your pin box to determine its replacement. I've linked an article to assist in this that shows you where to measure and then will give you what pin box you likely have so you can find the replacement options. Based on online pictures, it appears you may want the Trailair Flex Air...

  • What are the Maximum and Minimum Air Pressures PSI for a Lippert Trailair Pin Box?
  • I'm not familiar with the part number you mentioned, but according to Lippert, the air pressure for Trailair pin boxes like # LC155943 range from 20 to 120 psi. Lippert does not recommend a specific air pressure because it will vary for each application. After the pin box is installed, go ahead and hook up the trailer on level ground. There is a sticker on the front shock absorber that is used to ensure proper inflation. You should inflate the airbags until the arrows on the sticker...

  • 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...
