  • Absorbs Road Shock and Reduces Chucking
  • Lippert
  • 21000 lbs GTW
  • Fixed Turret

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.

  • Air ride pin box replaces standard pin box on your 5th-wheel trailer to cushion your ride, improve handling, and limit strain on truck and trailer
    • Minimizes chucking
    • Eliminates bounce and jarring
  • Internal air bag absorbs road shock
    • Scissor-like motion allows pin box to compress, compensating for jarring and bounce

  • Black powder coat provides rust resistance
  • Sturdy steel construction
  • King pin connects to any 5th-wheel trailer hitch
  • Bolt-on installation with no assembly required
  • Made in the USA


Specs:

  • Designed to replace Lippert 1116 5th-wheel pin box
  • Weight capacity: 21,000 lbs

Notes:

  • 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

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.

The product was great. The service was great. The freight company left a lot to be desired.



by:

There was a mix up with the order but once it got straighten out,they reshipped another one.I told them that I needed it by Friday,I don't know how but it made.it I would use this company again in the future.
Thanks



by:

etrailer is and excellent site to order parts for your trailer. They walked me thru the part numbers so the pin box I ordered fit. No problems with the install and I can't wait to take my first trip with the new pin box.



by:

Good packaging and received quickly.



by:

GREAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!



by:

The pin box works perfectly.



by:

The Trailair pin box is a great product.
I
installed it before a 700 mile trip and it does what it is intended to do. Etrailer was very helpful in selecting the correct pin box for my trailer.
Thank you.



by:

love it worked so good, love Etrailer also great company



by:

I just got the pin box, so I don't have it installed yet. It seems very well built. I wish it had a removable eye in the top so I could lift it with the crane that I have in the bed of my truck. No complaints though. Can't wait to try it out.



by:

We needed a longer pin box and one that would give a better ride. Spoke with representative from etrailer who was very helpful. It has made a huge difference in ride and maneuverability.



by:

Made a huge difference in the way to 5er tows now. Less bouncing and chucking, the coffee maker on the counter stays in place and things inside don’t move around anymore. It cut down on the stress to the 5er more than I expected, I can feel the difference in the driver seat also so it has been a very nice upgrade.



by:

There is a smoother ride now, but it didn't eliminate the push/pull effect completely while going down the highway as I was told by another it would do. All in all I am glad I bought it.



by:

Best ever. So glad I ordered this..easy to install and was just what I needed for our new 5th wheel toy hauler.



by:

Worked out great on my 2011 Cameo, wouldn't own another 5th wheel with one.



by:

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.



by:

Works great I can watch my golf cart trailer behind my fifth wheel



by:

Great phone assist prior to ordering as always and product was just as described. Shipping was a little hard to track as UPS advised the unit was sitting in our town but unable to locate for 5 days. E-Trailer is always awesome to work with. Thanks to all your staff.



by:

The trail air makes trailer ride so much better,very little chucking and a smoother ride it is very heavy but with a little help it was installed in no time. Thank you to etrailer for the fast shipping and great price.

It took about a month to get here but we are so glad it did. Thank y’all so much!

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.



by:

Really is a smooth ride after adding the air cushion pin box. Makes pulling a pleasure.



by:

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.

  • Solution for 2024 Keystone Montana High Country 295RL that Sits Nose High
    Hey Michael, so the Curt Trailair part # LC155943 that you referenced was not designed to offer a different ride height from the pin boxes it replaces so it would not be the way to go if you were wanting to make a height adjustment. What I would do is try the higher mounting bolts like you mentioned and see if that gets your trailer level while also keeping at least 6 inches of clearance between the bed rails and the trailer overhang. If that still does not fix the problem then you'd need...

  • How to Determine the Pin Box Manufacturer and Model on a 5th Wheel Trailer
    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. Once the pin box is identified we can determine if there is an air ride pin box that will fit.

  • Cushioned Pin Box Recommendation for 2007 Raptor Toy Hauler with Lippert 1116 Pin Box
    Can you lower the head of your fifth wheel hitch at all? Nearly every fifth wheel hitch has an adjustable height head. Typically you have to unbolt the head and then install it in a lower set of mounting bolts. The Trailair Pin Box part # LC155943 will work as a replacement for your Lippert 1116 and has an air bag to cushion the ride quality.

  • Best Cushioned Pin Box for 2019 Keystone Sprinter Limited with Lippert 1116 Pin Box
    For your 2019 Keystone Sprinter Limited Fifth Wheel trailer that has a Lippert 1116 pin box installed on it currently the best cushioned upgrade option we have is the Trailair part # LC155943 which uses an air bag and shock to cushion bouncing and jarring. This option will do the best to cushion the ride quality and also has more capacity than you'd need as it's rated for 21,000 lbs trailer weight.

  • Air Ride Pin Box for 2023 Keystone Cougar 320RDS
    Hi Peter; to find the right Air Ride pin box you will need to identify the pin box you currently have on your 2023 Keystone Cougar 320RDS. Start by looking for the sticker. If it isn't directly listed then the LCI number or serial number can be used to identify it. If you can send me that number I will be able to look it up after the weekend. You can also take a look at the help article below and measure to find the bolt pattern. Once you know which bolt pattern your current pin box uses...

  • Will the Reese Goose Box # RP85FR Replace My Pinbox on My Keystone Montana 3791RD?
    For your Montana 3791RD, I could not find the specs of the factory pinbox on that model. However, most Keystone fifth-wheel trailers do have the Lippert 1621 or 0719 pinboxes. I went ahead and attached pictures of the bolt spacing dimensions of both of these models so you can measure and compare to see what pinbox you have installed. If you confirm that you have these pinbox models, then the Reese Goose Box # RP85FR will work.

  • Replacement Trailair Flex Air Pin Box for 2021 Keystone Montana 3120RL
    In order to choose the correct Trailair Flex Air pin box like the # LC328492, or any other pin box for that matter, is by checking the spec sticker on the current pin box for a model number. We don't have a database that tells us what pin box is on specific trailers, so you would need to either find the number on the sticker/plate or you can take some measurements of the bolt patterns to determine which one you've got. I've linked a brief article that explains this process. The Trailair...

  • Is There Cushioned Pin Box for 2017 Keystone Raptor 412
    Your 2017 Keystone Raptor 412 has a Lippert 1116 pin box so for a cushioned replacement the Trailair part # LC155943 is the correct fit and would work great. There isn't a Flex Air that fits your trailer. Now if you are continuously breaking leaf springs that to me would indicate you are exceeding the weight capacity of the springs or are driving on very rough roads. Can you get back to me and let me know what springs you have and what the weight of your trailer is when loaded?

  • What Info Is Needed to Pick Out Replacement Cushioned Pin Box for Camper
    If you look on the pin box there should be a brand and model number listed on a sticker or plate. For example, you might find Lippert 1116 which is very common and what the Trailair part # LC155943 you referenced is designed to replace for a cushioned pin box. You may find a Lippert sticker with a serial number and LCI item number as well which I would have to send to Lippert to have them determine what it is. Let me know what you find on your pin box though.

  • What Curt Air Ride Pin Box Will Replace The LCI Part Number 20210182651
    Hello Mark. I had Lippert run the serial number for your pin box and yours is actually the Lippert 1621 bolt pattern. The Trailair Air Ride 5th Wheel Pin Box # LC155943 you mentioned is for the Lippert 1116 bolt pattern so this will not be correct. The correct Curt shock absorbing pin box is the following: - Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000 lbs # LC328492

  • Trailair Air Ride Pin Box Replacement for 1116 Pin Box on 2019 Keystone Montana
    The correct Trailair Air Ride pin box to replace the 1116 on your 2019 Keystone Montana is the part # LC155943 which is rated for up to 21,000 lbs. When I've reached out to manufacturers in the past they have said that the pin box needs to be an exact replacement and it has everything to do with the design and leverage of the trailer to the pin box. Using a different design could very well damage your towing setup which would likely cost more than the price of a pin box to fix.
