Video Transcript for Lippert Trailair Air Ride and Flex Air 5th Wheel King Pin Shock Review
Hey everybody, how's it going Today we're gonna be going over and showing you how to install the replacement shock absorber here for a Lippert Trailair and CURT Flex Air fifth-wheel pin boxes. So in regards to compatibility, this shock here actually works here with a couple of different pin box models. Whether you have the Ultra-Fab, Flex Air, you have any of the Trailair, Air Ride pin boxes or you have the CURT Flex Air, this shock here is gonna be an exact fit replacement. Now, this is an exact OEM-direct fit replacement part. This isn't made by another manufacturer. This is made directly by the manufacturer, the pin box.
So, it's gonna be an exact bolt-on fit and it's gonna be the same quality as the pin box that we have here. So Lippert actually changed the design of this shock absorber here on their older models that we're branded under Trailair. They used a sticker that had the fill line in there, but the problem was that, is that sticker over time would wear off and it'd eventually work itself loose from the shock absorber. Therefore, we'd lose that mark that we need to inflate our air bag too. Well, they've actually redesigned the shock absorber to now it's actually etched into the inner tube here.
You can see the "Inflate to this line." There's an arrow, and then we have our line up here. So it's actually etched into the shock absorber now so you don't have to worry about that sticker falling off. So the missing sticker is one reason you would wanna replace your shock absorber. Another one is if the shock absorber is worn out, because these do fail over time, depending on how hard we're using them or how long they've been installed. Now, we're kind of playing this by feel in regards to how to tell if the shock absorber is bad.
Basically, if you experience excess bouncing here with your pin box here, that means the shock absorber is not returning to the normal position, and therefore that would indicate it's faulty. And if we also take it off and just sort of play with it by hand, it should be pretty easy to compress and retract by hand, that would indicate its faulty. This one takes a lot of force. Almost as much as I'm able to give it in order to compress and retract it. So that would indicate that this is working correctly, but if it moved really easily by hand, that would indicate it's faulty and would need to be replaced.
So a lot of it's just playing with it by feel, sort of feeling how the trailer rides as it was new and replacing it based on those criteria. So the first step of our installation, we do need to make sure we release all the air pressure from our airbag. And then we're gonna come up top here with a 3/4 inch socket and wrench and begin by removing this top bolt here. So, now we're gonna slide the bolt out. Now there's a little bit of tension on that bolt now. So what I'm gonna do is I'm just gonna sort of press up on the bottom of the pin box a little bit, should give us enough leverage to pull the bolt out like so, and then our shock absorber should just tilt down. Now we use that same combination of our 3/4 inch socket and wrench and we'll remove that bolt on the bottom as well. Go ahead and slide our bolt out, and our shock should come out next. Next, we're gonna take our shock assembly here. We wanna make sure that this decal here with our inflation line is facing out away from the pin box. We also want to ensure that the outer sleeve is gonna be attached at the top here. The inner sleeve is gonna go towards the bottom. So we'll go ahead and set it into position now. We'll take our factory hardware here, our factory bolts that we removed. I'll go ahead and thread that on, just loosely thread that, and then I'm going to line up the one on the top. So in order to do that, we're again gonna have to lift up from the bottom of the pin box. It doesn't take a lot of force. Get our bolt started there. Once we have that through, we'll install our nyloc nut. And then we'll come back with our 3/4 inch wrench and socket and tighten those down. Now there isn't actually a torque spec provided with these. The manufacturer does not specify, so we're just gonna be doing it by feel. With the nyloc nut, as soon as you get the nylon through the threaded nut there, that's gonna serve its purpose there. You don't have to worry about it backing out. You don't wanna get it too tight, but again we're just gonna be doing most of this by feel. You can sort of gauge how much pressure it took to release that nut. That's about how much we're gonna tighten it. Unfortunately, we just don't have exact torque specifications, so we do need to do this by feel, and use our best judgment. So now, once we have both of those bolts tightened down, that's gonna do it today, for our look at the replacement air shock, for our Lippert Trailair and CURT Flex Air fifth-wheel pin boxes..

Great customer service, friendly and able to answer any questions asked.

Replacement part that works fine.
by: Gerald11/07/2023
Did not receive the shock, receive the other two parts. Only valve stem, and air spring was in the box
by: Sidney06/20/2023
Fits my pin box and cushions the ride of both the camper and my truck. The markings on the outside indicating how much air is to be put in the bladder were wrong but etrailer gave me a pressure range to go by and it works well.
by: lockcop09/27/2018
Decal a little buggered up so I made my own out of reflective tape.
by: Raymond12/14/2019
Perfect replacement shock absorber for the Flexair hitch on our Redwood fifth wheel. We had a mishap that left the original with a bent case and it was difficult to set the pressure in the air bags as it would often stick. Simple to install and has my has my hitch back to proper operation. Ordering process was easy, part arrived on time in perfect condition.

The replacement shock is still performing as it should.
by: David 10/18/2023
Great product and with no sticker to take care of is even better!
by: Thomas 03/18/2023
I love the parts. I also purchased the air bag for the hitch. It all came to me as agreed.
by: Dale L.07/06/2020
I ordered replacement shocks for my trailair hitch. they arrived on the promised delivery date and were identical to the OEM shocks. The ride of the trailer improved, the old shocks were 10 years old.

I bought 2 new shocks for my trailair fifth wheel hitch a d they are working out very well.
by: Ken E.07/27/2019
I chose Etrailer parts because they had a good selection of high quality replacement parts for my AirRide 5th wheel hitch (and everything else I need for my truck and trailers). My original equipment was very old, and I expected it to be impossible to find a replacement that fit, but George at Etrailer had them NEW. I installed the parts a year ago and I have been very happy. The quality is clear after a year of hard use--the parts still look and perform like new (better than the rest of the trailer!). The pictures show it ... the shock absorber and air bladder and steel yellow valve stem still in top shape with almost a thousand miles on them. So glad I have Etrailer a try!

Great
by: Philip02/05/2018
Easy to replace, and made a huge difference on the comfort of the ride in my truck. Noticed that I needed a new one when it took extra air pressure in the air bag to raise the shock to the proper height. Wish I had noticed that earlier. Well worth replacing, and the service from etrailer has always been top notch. Got a B&W fifth wheel hitch earlier, and that is completely amazing!! Worth every penny!
by: Mike05/30/2022
The shock was a Lippert componentfrom what I could tell, at a good price and etrailer's better than average delivery. Added it to our DRV Mobile Suites 36' system to help soften the Pinbox recoil of the airspring going over rough bridge transitions.
by: Len 02/17/2020
I have not had a chance to install my new shock absorber. After I have installed it and tested it, i will write a better review. I was very happy with the order process and the delivery.

The product works perfectly. Exact replica of what I replaced. Good price and speedy delivery. Happy camping.
by: Lewis 06/06/2023
Parts fit as expected
by: Virgil02/11/2022
The visual appearance was not what I was expecting. The paint was very scuffed as shown in the pictures. It appears to have been in your inventory for a long time an potentially handled roughly.
Hopefully it will be functionally fine.

After receiving the replacement shock, I took it out of the package, got my socket set and installed in five minutes. Easy install. If I needed another, I would purchase this one.
by: Jeffery01/24/2019
Product arrived in just a few days. It was easy to install and only took 10 minutes. Great service from etrailer staff with help on finding the correct item for my Flex Air 328492 king ping.
by: Bob S.09/10/2016
I replaced the shock on my Flex Aire pin box that had been damaged due errant parking. It was a diprect replacement first all, two day shipment, simple, easy to install and I feel confident of the future performance. This a great set up too, smooth riding all the way.
by: John C12/18/2020
Needs to have the full pressure marking like the original shock has. Would make it much easier to know when you are getting the proper amount of air in the bladder.
by: Allen S.07/06/2018
Great customer service. We were camping and needed a shock for the pin box. Called etrailer ordered the part and it arrived at the campground on the day it was supposed to. I will continue to do business and will highly recommend etrailer. Thanks again!!!

- Replacement Air Spring for Flex Air 18,000 lb Pin Box with Long JawI reached out to my contact at Lippert and was able to confirm that the Replacement Air Spring for Trailair 5th Wheel Pin Boxes # LC432404 is the correct replacement for your Flex Air 18,000 lb Pin Box with Long Jaw. While I wasn't able to find any information or cross-reference the LC13896531 model number, I can confirm that Lippert used the same air bag on all of their Flex Air pin boxes, including yours, as well as the current models listed below: # LC328492 - L05 Flex Air - Lippert...

They stated that the arrow on the shock is just a reference point and not something that you should really use as your absolute guide as they have had issues with the sticker being misplaced. The reason that the ride is so rough is that you are at near max psi of the airbag which is 120 psi. They recommend that you adjust the pressure...

I reached out to the manufacturer, Lippert, about the correct replacement shock and air bag for your Trailair Tri-Glide pin box. They told me you will be able to use the Replacement Shock # LC177223 as well as the Replacement Air Spring # LC432404 on your Tri-Glide.
view full answer... - Correct Replacement Air Bag and Shock for Trailair 5th Wheel Pin BoxThe correct replacement air bag and shock for a Trailair 5th Wheel Pin Box is the Replacement Air Spring part # LC432404 and the Replacement Shock part # LC177223. Unfortunately, the average life span would vary greatly by the amount of use so I don't have any sort of timeline to provide. I have attached for you below install videos I did on each of these components if you have trouble getting them on.
view full answer... - Are Replacement Parts Available for the Trailair Air Ride 5th Wheel Pin BoxesThe reason that you cannot find the replacement shaft is because Lippert does not offer this separately. If the shaft is worn or damaged then it is time to replace the pin box. There are only very minimal replacement parts for these pin boxes (valve part # LC156740, shock part # LC177223, airbag part # LC432404) and this is intentional to discourage home repairs on such a critical component. That said, this might be a good to time to upgrade from the Trailair Air Ride 5th Wheel Pin Box...

- Flex Air Replacement Shock AvailabilityIt's hard to see the dent in the picture you submitted so it's harder to say but it looks like it's probably fine. I'd probably take it on a short trip around the block keeping and eye on it and see if it works like it should. If you find you need a replacement you'd want the part # LC177223.

- Replacement Shock Recommendation for Trailair Pin BoxSounds like you are looking for a replacement shock for the Trailair pin boxes. For that you would want the part # LC177223 which is exactly what you'd need.
view full answer... - Air Bag Inflation Instructions On Trailair Pin Boxes With 18,000 lb CapacityThere are a couple different Trailair pin boxes for the 18,000 lb capacity. There is the Flex Air like # LC328492 and the Air Ride like # LC179879. With either model, the air bag should be inflated until the outer cylinder of the shock rises high enough to fully expose the yellow inflation indicator sticker that you can see in its entirety on part # LC177223. There is not a listed max psi.
view full answer... - Trail Air Pin Box Shock and Air Bag Replacements?What you're experiencing is exactly what a Trailair is supposed to suppress and would tell me that some of your components are worn down. While some chucking is inevitable, your shock shouldn't really move freely like you're suggesting, so replacing the shock would likely help fix some of your current problems. I can't say that I've seen a Trailair pin box that has a 24,000-lb capacity; I've only seen them go up to 21,000-lbs. If you do end up having a 21000-lb version opposed to a 24000-lb...

If you have the # LC369535, then you will want the Replacement Air Bag For Trailair 5th Wheel Pin Boxes - Qty 1 # LC432404 instead. If you also need a new valve, you can use the Replacement Pin Box Tank Valve for Lippert or UltraFab TrailAir Pin Boxes # LC156740.

The highest I have seen is 21K and the air bag for those and some 18K models is # LC432404. There should also be some information on your existing air bag if you can take it out. For the shock use # LC177223.

It sounds like you are not getting those benefits so air pressure adjustment would be the simplest potential fix. The internal air bag should be inflated (with the loaded trailer hitched) until the outer cylinder of the shock rises high enough to fully expose the yellow inflation indicator sticker.

- How the Shock Works on Trailair Air Ride and Flex Air 5th Wheel King PinsThe Replacement Shock for Trailair Air Ride and Flex Air 5th Wheel King Pins, part # LC177223, is a shock that also serves as a dampener for kickback. What that means is this shock works in conjunction with the king pin's air bag to absorb road shock from bumps. This keeps the air bag from bursting. Then, after everything is compressed, it dampens the kickback (upward rebound) from the air bag to its natural position. This position is not fully extended like a traditional air bag suspension....

- Is Uneven Shape of Trailair Pin Box Air Bag a ProblemThank you for the photo of your TrailAir pin box's rubber air spring. The shape/position of the bag are not necessarily an issue. Just in case I do suggest that you check that your air bag is inflated to the correct pressure. There is a simple way to determine the correct pressure. Hitch your trailer and them slowly add pressure through the air bag's Schrader valve. Add pressure until the two black arrowheads on the yellow sticker on the shock are just visible.
